Evaluate 12k - h2 when h=2 and k=3

32

Step-by-step explanation:

We need to find 12k - h² , where

Subsitute upon respective values ,

=> 12k - h² = 12*3 - 2²

=> 12k - h² = 36 - 4

=> 12k - h² = 32

you never say the total so we cant find the percentage used for petrol

step-by-step explanation:

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
