Jill uses two sides of a right triangle to find the sine of one of the acute angles and gets that the sine of that angle is 2.4. Did Jill make a mistake? Explain or support your answer

139 divided by a number

step-by-step explanation:

8.75

how-to:

first, we need to find what we have to work with.

since i know that we have 7 (years) and 0.8 (inches), we can use these to solve and find the equation!

secondly, what you want to do, is see that we need to know how much growth out of the 0.8 inches he got in only 1 year, instead of 7 years.

let's try to divide.

7 ÷ 0.8 = 8.75

yes, i think so although i am not sure. this is a very strange question.

the answer is  

c.

90.0π cm^2

hope you got it.
