Question

Find the measure of angle B

Answer 1

The answer to your question is: 39° second option

Explanation:

The sum of the internal angles in a triangle equals 180

Then

90° + (2x + 11)° + (4x - 5) = 180°

90° + 2x + 11 + 4x - 5 = 180 Reduced like terms

6x = 180 - 96

6x = 84

x = 14

B = 2(14) + 11

B = 28 + 11

B = 39°
