Answer 1

Question 1:
We have an isosceles triangle.
x = 180 - 2(68)
= 44

The second choice is your answer.

Question 2:
Since we have an isosceles triangle,
3x + 8 + 5x + 12 = 180
8x + 20 = 180
Subtract both sides by 20
8x = 160
Divide both sides by 8
x = 20

The third choice is your answer.

Have an awesome day! :)

Answer 2

1 is 180 - 2(68) = 180 - 136 = 44
2 is
5x + 12 + 3x + 8 = 180
8x + 20 = 180
8x = 160
x = 20
