The measure of angle B from the given diagram is 35 degrees
What is a rectangle?
A rectangle is a 2 dimensional shape with 4 sides and angles. The measure of its interior angles are all equal to 90 degrees
Find the required diagram of the rectangle attached. From the figure, you can see that the measure of angle A and angle B are complementary that is:
m<A + m<B = 90 degrees
Given the following parameter
m<A = 55 degrees
Substitute to have:
m<B = 90 - m<A
m<B = 90 - 55
m<b = 35 degrees
Hence the measure of angle B from the given diagram is 35 degrees
