Find the x.

10

Step-by-step explanation:

1. Write an equation to represent the ratio of the sides to the corresponding sides in the second figure.

6/9 = x/15

6 and x are both numerators because they are corresponding sides and 9 and 15 are both numerators because they are corresponding sides.

2. Solve for x.

multiply both sides by 9

6 = 9x/15

multiply both sides by 15

90 = 9x

solve for x by dividing both sides by 9

x = 10

*sorry if the explanation was confusing but I hope you understand with the equation and numbers

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
