A ramp is designed with the profile of a right triangle. The measure of one acute angle is 5 times the measure of the other acute angle. Find the measure of each acute angle. a. 18°, 72° c. 15°, 75°
b. 4.5°, 85.5° d. 9°, 81°

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
