The measure of ∠BCD is 145°. The measure of ∠ABC is 65°.
What is measure of ∠BAC?
115°
35°
80°
145°
Answers
Answer:
m∠BAC = 80°Step-by-step explanation:
m∠BCD = 145° ⇒ m∠BCA = 180° - 145° = 35°
From ΔABC:
m∠ABC + m∠BCA + m∠BAC = 180°
65° + 35° + m∠BAC = 180°
m∠BAC = 180° - 100°
m∠BAC = 80°

Answers
Step-by-step explanation:
⇒12)It is an arithmetic sequence.
d=2-1=3-2=4-3=1
a(n) = a +(n-1)d
a(n) = 1+(n-1)1
The next three terms:
a(6) = 1+(6-1)1=6
a(7) = 1+(7-1)1=7
a(8) = 1+(8-1)1=8
⇒13)It is an arithmetic sequence.
d=0-3=-3-0=-6+3=-3
a(n) = a +(n-1)d
a(n) = 3+(n-1)-3
The next three terms:
a(5) = 3+(5-1)-3=-9
a(6) = 3+(6-1)-3=-12
a(7) = 3+(7-1)-3=-15

Based on the measurements shown on triangle ABC, AB must be?
Answers
Answer: B. 7 and 10 ft
Step-by-step explanation:
The first thing to do is to look at the triangle’s angles. One of them is missing right? So you need to find that missing angle. All the angles in a triangle add up to 180 degrees. Therefore you need to add 68 and 47. Your total must be subtracted by 180.
Your problem will look like this
68+47=115
180-115=65
Your missing angle is 65The angle correspond to the sides. You need to look at the opposite of the angle to figure out the number of the side.
For example Angle A opposite = 7
Angle B opposite is 10
notice that Angle B degree is 68 which is the largest degree. And Angle A degree is 47 which is the smallest degree.
The largest degree will always be equal to the largest side
The smallest degree will equal to the smallest side
can someone solve -192= -6 (6x - 4) step by step?
Answers
Answer:
x= 4 2/3 OR 14/3 OR 4.6... –– 4 2/3 and 4.6... are the simplest form.
Step-by-step explanation:
Your original equation is -192 = -6 (6x - 4):
1. -192 = -6 (6x - 4)
Use distributive property and multiply: -6 x 6x = -36x and -6 x -4 = 24:
2. -192 = -36x + 24
We now move the +24 onto the other side of the equation, -192. Add 24 onto -192 and since we're moving the 24 on the left side of the equation, 24 will removed, so -24 on the right side of the equation:
3. -192 + 24 = -36x + 24 - 24
Divide both sides of the equations by -36 to get "x" by itself:
4. -168 / -36 = -36x / -36
Simplify the fraction of 24/36 by 12:
5. 4 24/36 = 4 2/3 or 14/3 or 4.6... = x
4 2/3, 14/3, 4.6... = x

If there is a base of 9 and a area of 12 how do you explain how to find the height.
Answers
Answer:
height = 8/3
Step-by-step explanation
I'm assuming that this is a question to a triangle. So since an area of a triangle is 12 you solve by the formula 1/2(base)(height). You would solve for height so your equation would look smth like this: 12 = 1/2(base)(height). So you would end up with 24/8 which would simplify to 8/3.
