Answer:

108 degrees

Step-by-step explanation:

x + 63 = 8x (vertically opposite angles)

7x = 63

x = 9

8x + angle1 = 180 (sum of angles on a straight line)

8(9) + angle1 = 180

angle1 = 180 - 8(9) = 108

What's the length of AB?

Nastasia [14]

Use the pythagorean theorem to solve this: a^2 + b^2 = c^2.
You already have a and b which are 3 and 4. Square them up and you will get 9 + 16 = c^2.
Add.
25 = c^2
Lastly, square root both sides.
5 = c
The length of AB is 5.
