Lamar receives money from his relatives every year on his birthday. Last year, Lamar received $100. This year, he received 29% more than last year. How much did he receive this year?

$129

Step-by-step explanation:

Amount received last year = $100

Amount received this year = x

x = 29% more of last year

x = $100 + ($100 * 29%)

x = $100 + ($100 * 29 / 100)

x = $100 + $29

x = $129

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
