Work out the size of AED. Work out x
Answer:
a). m∠AED = 70°
b). x = 10°
Step-by-step explanation:
a). Quadrilateral ABDE is a cyclic quadrilateral.
Therefore, by the theorem of cyclic quadrilateral,
Sum of either pair of opposite angle is 180°
m(∠AED) + m(∠ABD) = 180°
m(∠AED) = 180° - 110°
m(∠AED) = 70°
Since, ∠AED ≅ ∠EAD
Therefore, m∠AED = m∠EAD = 70°
b). By triangle sum theorem in ΔABD,
m∠ABD + m∠BDA + m∠DAB = 180°
110° + 40° + m∠DAB = 180°
m∠DAB = 180° - 150°
m∠DAB = 30°
m∠BAE = m∠EAD + m∠BAD
= 70° + 30° = 100°
By angle sum theorem in ΔACE,
m∠EAC + m∠AEC + m∠ACE = 180°
100° + 70° + x° = 180°
x = 180° - 170°
x = 10°

What is the probability of the following.
(a) An event A that is certain to occur?
(b) An event B that is impossible?
Enter an exact number
Answer:
(a) The probability of an event A that is certain to occur is 1.
(b) The probability of an event B that is impossible is 0.
Step-by-step explanation:
The probability of an event can be described as the chance that the event will occur.
The probability that an event will occur is between 0 and 1.
Based on the above, we can answer as follows:
(a) What is the probability of an event A that is certain to occur?
The probability of an event A that is certain to occur is 1.
(b) What is the probability of an event B that is impossible?
The probability of an event B that is impossible is 0.
write a linear equation that has a slope of 1/2 and a y-intercept at the origin. (y=1/2x) (y=0x+1/2) (y=1/2x+1/2) (y=-1/2x)
Answer:
The linear equation with given slope and y-intercept is:
Option 1: [tex]y = \frac{1}{2}x[/tex]
Step-by-step explanation:
The slope-intercept form of equation is given by:
[tex]y = mx+b[/tex]
Here
m is the slope of the line and b is the y-intercept.
Given that
Slope of line is 1/2 so m = 1/2
And y-intercept is on origin so b = 0
Putting the values we get
[tex]y = \frac{1}{2}x+0\\y = \frac{1}{2}x[/tex]
Hence,
The linear equation with given slope and y-intercept is:
Option 1: [tex]y = \frac{1}{2}x[/tex]
The graph shows the function f(x) =2*x what is the value of x when f(x)=8
Answer:
f(x)= 2ˣ
We have to find x when f(x) is 8
8=2ˣ
we can write 8 in exponential form as 2³
2³=2ˣ
here base is same (2) on both left and right side
comparing the powers we get
x=3
:)
Answer:
x=4
Step-by-step explanation:
since f(x )=8
8=2*x
we divide by 2 both side
so,
x=4

Answer:
Pretty sure is 42
Step-by-step explanation:
5+10+8=23
65-23=42
The number of men will be 42 if there are 5 hens, 10 goats, and 8 cows.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have:
In one house, there are 5 hens, 10 goats, and 8 cows.
Let H be man's head
H < 65
Total heads = 5 + 10 + 8 =23
Man's heds = 65 - 23 = 42
Thus, the number of men will be 42 if there are 5 hens, 10 goats, and 8 cows.

3x + 1 = 10
Step 2: Solve for x
Subtract 1 on both sides: 3x = 9Divide 3 on both sides: x = 3Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 3(3) + 1 = 10Multiply: 9 + 1 = 10Add: 10 = 10Here we see that 10 does indeed equal 10.
