Convert 45°c to fahrenheit using the formula f= 5 c + 32.
o 81°f
o 113°f
o 57°f
o 138.6°f

113°F

I used a different way but here is the answer

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

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
