Plot point C in GeoGebra to verify that it indeed lies on . You can enter the coordinates in the Input window to plot the point. Also, verify the distances you calculated in question 3 using GeoGebra. Take a screenshot showing the distances displayed by GeoGebra, and paste it below.

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

hello,

as   long as they add up to 180 its correct.
