Mrs. Smith works at a music store. Last week, L, she sold 6 more than 3 times the number of CDs she sold this week, T. Mrs. Smith sold a total of 110 CDs throughout the 2 week period. Which system of equations represents the number of CDs she sold last week and this week?

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

the answer is c hope this
