What is the measurement of the angle b. explain.

65

Step-by-step explanation:

Total degrees in triangle: 180

Angle 1= 50

We know that the other two angles are equal, so set it as "2x"

50 +2x= 180

2x=180

x=65

angle b is 65

Step-by-step explanation:

it states in the description below the question that the 2 missing angles are equivalent to each other. A triangle no matter what, ALWAYS has all it's interior angles equal to 180 degrees.

180-50= 130

130÷ 2 = 65

65 degrees is your answer
