Answer: 110
Explanation: all 3 angles have to add up to 180.
Both the right and left angles are the same and since the left angle is 35 degrees we can safely conclude the right angle is as well, so all you have to do is is both of the 35 degree angles together which gives you 70, then subtract it from 180. 180-70=110 so that is the angle of 1. and since the bottom and top are the same the angle of 4 is also 110

[tex] \boxed{ \boxed{ \tt{ \: 4. \: \: \: \: \: \: \: \underline{13 \sqrt{3} \: cm}}}}[/tex]
Step-by-step explanation:
First , A simple way how to remind the three basic trigonometric functions is by reminding the famous word " SOHCAHTOA". We divide the word in three words with three letters.
[tex] \underline{ \underline{ \sf{SOH , \: CAH , \: TOA}}}[/tex] :
The first letter of each word represents the name of the function.The second letter represents what's up the ratios sign.The third one represents what's at the bottom of the ratio sign.We write :
[tex] \sf{sin \: \theta = \frac{opposite}{hypotenuse} }[/tex][tex] \sf{cos \: \theta = \frac{adjacent}{hypotenuse}} [/tex][tex] \sf{tan \: \theta = \frac{opposite}{adjacent}} [/tex]Now , Let's work on it :
3. Based on the figure ( 3 ) , we know the hypotenuse ( i.e 15 ) & the angle 53° & we have to find the opposite ( x ).
[tex] \sf{ \sin(53) = \frac{opposite}{hypotenuse} }[/tex]
⇾ [tex] \sf{0.79 = \frac{x}{15}} [/tex]
⇾ [tex] \sf{x = 11.85}[/tex]
----------------------------------------------------------------
5. Based on the figure ( 4 ) , we know the adjacent ( i.e 13 cm & the angle 60° & we have to find the opposite ( x ).
[tex] \sf{ \tan(60}) = \frac{opposite}{adjacent} [/tex]
⇾ [tex] \sf{ \sqrt{3} = \frac{x}{13} }[/tex]
⇾ [tex] \sf{x = 13 \sqrt{3}} [/tex] cm
And we're done !

Find the distance between the two points rounding to the nearest tenth (if necessary) (-1,-2) and (5,2)
Answer:
Distance between the two points
AB = √52 = 7.2111
Step-by-step explanation:
Explanation:-
Given points are (-1,-2) and (5,2)
Distance formula
[tex]= \sqrt{(x_{2}-x_{1} )^{2} +(y_{2} -y_{1})^{2} }[/tex]
[tex]= \sqrt{(5-(-1) )^{2} +(2 -(-2))^{2} }[/tex]
[tex]= \sqrt{(6 )^{2} +(4)^{2} }[/tex]
= √36+16
=√52
= 7.2111
Final answer:-
Distance between the two points
AB = √52 = 7.2111
Find the value of x.
Answer:
x = 26
Step-by-step explanation:
If angle a and b are congruent, then set 68 and 4x + 8 together to equal to 180 on the right side. Combine 68 and 8 together to get 76. Then, subtract 76 on both sides to get 104 on the right side. Divide that number by 4 to get your x-value which is 26.

An internet download speed is 4.2 MB/S (constant). How long will it take to download a 30 GB file?
And with 900 KB/S?
Answer:
Time with 4.2MB/S speed = 7314.3 seconds
Time with 900 KB/S speed = 34952.5 seconds
Step-by-step explanation:
Given that:
Internet download speed = 4.2 MB/S
File to download = 30 GB
1 GB = 1024 MB
30 GB = 30*1024 = 30720 MBS
Time required = [tex]\frac{30720}{4.2}[/tex]
Time required = 7314.3 seconds
With 900 KB/S
1 MB = 1024 KB
30720 MB = 30720 * 1024 = 31457280 KBS
Time = [tex]\frac{31457280}{900}=34952.5\ seconds[/tex]
Hence,
Time with 4.2MB/S speed = 7314.3 seconds
Time with 900 KB/S speed = 34952.5 seconds
Answer:
Time with 4.2MB/S speed = 7314.3 seconds
Time with 900 KB/S speed = 34952.5 seconds
Step-by-step explanation:
Given that:
Internet download speed = 4.2 MB/S
File to download = 30 GB
1 GB = 1024 MB
30 GB = 30*1024 = 30720 MBS
Time required =
Time required = 7314.3 seconds
With 900 KB/S
1 MB = 1024 KB
30720 MB = 30720 * 1024 = 31457280 KBS
Time =
Hence,
Time with 4.2MB/S speed = 7314.3 seconds
Time with 900 KB/S speed = 34952.5 seconds

You have $4.30 in your piggy bank with only nickels and quarters. You have 8 more nickels than quarters. How much of each coin do you have?
show work
PLEASE I NEED HELP ASAP
Answer:
13 quarters and 21 nickels
Step-by-step explanation:
In this problem, a random person has $4.30 in his/her piggy bank. That is only nickels (0.05) and quarters (0.25). There are 8 more nickels than quarters. With that info, I can use the equation 0.25x + 0.05(x + 8) = 4.3 to figure out how many nickels and quarters there are.
0.25x + 0.05(x + 8) = 4.3 (Use the distributive property to multiply 0.05 by x and 8)
0.25x + 0.05x + 0.4 = 4.3 (Add 0.25x to 0.05x to get 0.3x)
0.3x + 0.4 = 4.3 (Subtract 0.4 from both sides)
0.3x = 4.3 - 0.4 (Subtract 0.4 from 4.3)
0.3x = 3.9 (Divide both sides by 0.3)
x = 3.9/0.3 (Divide 3.9 by 0.3)
x = 13
Knowing that there are 8 more nickels than quarters, I can degree there are 13 quarters and 21 nickels.
Substitute x for 13 in the equation to see if this is true.
0.25(13) + 0.05(13 + 8) = 4.3
3.25 + 0.05(21) = 4.3
3.25 + 1.05 = 4.3
4.3 = 4.3
So, x is 13.
There are 13 quarters and 21 nickels do we have.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
$4.30 in your piggy bank with only nickels and quarters. You have 8 more nickels than quarters
0.25x + 0.05(x + 8) = 4.3
Apply distributive property
0.25x + 0.05x + 0.4 = 4.3
0.3x + 0.4 = 4.3
Subtract 0.4 from both sides
0.3x = 4.3 - 0.4
0.3x = 3.9
Divide both sides by 0.3
x = 3.9/0.3
x = 13
Hence, there are 13 quarters and 21 nickels we have.

In a survey of 100 full-time students at a certain college, 62 were employed at least part-time.
Answer:
62%
Step-by-step explanation:
This one's easy to solve as a percentage because the total number was 100 to begin with. Simply divide the number of employed students by the total amount of students, 62/100, which gets 0.62, or 62%.

When solving this equation: -16 + x = -15 we start with adding 16 to both sides. Why do we use addition?
Answer:
So you can cancel out the 16. See, the -16 is negative, and if we add +16 to it, then it cancels out and is 0. That way, you have x=1.
Step-by-step explanation:
-16x+x=-15
+16x +16
0+x=1
x=1
