Answer 1

x=5

Explanation:

Angles Q and R are supplementary

13x + 21x +5 = 180

10+34x =180

34x=170

x = 5

Answer 2

x = 5

Explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

21x + 5 is an exterior angle of the triangle , then

21x + 5 = 5 + 13x + 40

21x + 5 = 13x + 45 ( subtract 13x from both sides )

8x + 5 = 45 ( subtract 5 from both sides )

8x = 40 ( divide both sides by 8 )

x = 5
