What equation should i write?

6t = 9

Step-by-step explanation:

The two pieces of tape are the same length and one tape represents 9 while the other represents 6 pieces of t. Thus, the equation should be:

6t has the same length as 9.

6t = 9

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2

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
