Jimmy is a carpenter. The graph shows the number of chairs that he assembles and the amount of time it takes him.

The equation that relates the number of chairs he assembles, c, and the number of hours he works, h, is c =
h.

If he spends 4.5 hours assembling chairs, the number of chairs he assembles is
.

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
