Represent the measurement of angle B in the figure.



In the figure, angle A and angle D are complementary. The measurement of angle D is 45°. Complete the equation to solve for b, the measurement of angle B.

180 =
+ (90 –
) + b

Answer 1

angle b is 45° as it is alternative angle of d so equal to d.

Explanation

now....

180 = 90+(90-45)+b

90+45+45

90+90

Answer 2

angle b is 45° as it is alternative angle of d so equal to d.

Explanation

now....

180 = 90+(90-45)+b

90+45+45

90+90

=180
