Help me with the step to this please I am trying to teach my daughter and I am completely lost!

x ≈ 76.5 ft

Step-by-step explanation:

Assuming this is a right triangle, then

Using the sine ratio

sin40° = =

Multiply both sides by 119

119 × sin40° = x, thus

x ≈ 76.5 ft ( to the nearest tenth )

do your own work and don"t cheat.

step-by-step explanation:

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
