Question

Find the measure of b and a. (type the number of the angle measure ONLY)

Answer 1

Explanation:

A straight line has 180 degrees.

43 + b + 50 = 180 Collect like terms

b + 93 = 180 Subtract 93

b = 180 - 93

b = 87

a + b + 75 = 180 All triangles have 180 degrees.

a + 87 + 75 = 180 Combine like terms

a + 162 = 180 Subtract 162 from both sides

a = 180 - 162

a = 18
