Question

Problem 18. Find x and y

Answer 1

x = 39°

y = 90°

Explanation:

Answer 2

x = 39°

y = 92°

Explanation:

x = 39° because alternate (or z) angles are equal.

x = 92° because all angles in a triangle add up to 180°.

so

49+39=88

angles on a straight line are equal to 180°

180°-88° = 92
