A leg of a right triangle is labeled 10 cm and one of the acute angles of the right triangle is 30 degrees Which of the following trig equations could be used to find the hypotenuse?

cos30°=10/x

cos30(x)= 10

0.866x=10

x=10/0.866

x=11.5 or 12

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✌✌✌
