You score 86 points on the test, and your friend scores 76 points. a. write a system of linear equations that represents this situation. let x represent the number of points a multiple choice question is worth and y represent the number of points a short response question is worth.

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

i think the length is 12 and the width is 17

your answer   is c
