Question

Find the measure of angle b. And show work

Answer 1

Answer:

From the above attachment we can conclude that the sum of the angle 'b' and 40° is 90° (right angle)

$b + 40 ^\circ = 90 {}^{ \circ} \\ b = 90 {}^{ \circ} - 40 {}^{ \circ} \\ \boxed{ b = 50 {}^{ \circ} }$

• b = 50° is the right answer.
