∠5 and ∠6 are complementary angles.
m∠5=13°
what is the measure of ∠6 ?

The two angles are complementary, which means that they must add to 90 degrees. This is by definition of what "complementary" means.

let x = measure of angle 6

(measure of angle 5) + (measure of angle 6) = 90 degrees

13 + x = 90

x+13 = 90

x+13-13 = 90-13

x = 77

So the final answer is 77 degrees

Arhombus is a quadrilateral.
