Step-by-step explanation:
Adjacent angles are when the 2 angles have a common vertex and a common arm.
if the exterior sides of 2 adjacent angles are perpendicular, then the angles are complementary angles.

When 2 angles add up to 90°, they are called a pair of complementary angles.
G(5)= 5 squared which is 25 minus 4 is 21
