Frida Kalo purchased an office chair for $167.87. She received a $19.95 rebate from the manufacturer and an $8.95 rebate from the store. The sales tax in her state is 5.5%. What is the final price? (Remember that tax is pre-rebate.) Please NO links with explanation :)

you can't solve x because it is 2 linear equation and you only have one equation

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
