The measure of angle b is 25°.
Solution:
Given data:
The "L" shape angle is a right angle.
Right angle is splitted by another line and two angles are formed.
One angle is 65° and the other angle is b.
Let us find the other angle b.
65° + m∠b = 90°
Subtract 65° from both sides of the equation.
m∠b = 90° – 65°
m∠b = 25°
Hence the measure of angle b is 25°.
