Question

Find the measure of angle b.

And show work

Answer 1

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.
