Mindy makes 6 dozen chocolate chip cookies. She takes 20 minutes to make all the cookie batter, and then she puts the cookies in the oven for 8 minutes per dozen.
To find how much time Mindy takes to make all the cookies, identify the hidden question.

Below

Step-by-step explanation:

You need to use SOH CAH TOA to find theta.

Looking at the triangle, we have the opposite side which is 9 and the adjacent side which is 10. This means you have to use Tangent to find theta.

Tan θ = opposite/adjacent

Tan θ = 9 / 10

       θ = tan inverse ( 9 / 10 )

       θ = 41.98

       θ = 42 degrees
