The attached table is one that it is convenient for you to memorize as long as you're taking courses involving angles. For the inverse functions, find the column corresponding to the function, then look for the value in that column. The angle at the beginning of that row is the answer to your question.

Step-by-step explanation:

First, we need to find the GCF (greatest common factor) of each of the number.
1. List out the prime factors of each of them.
2. Multiply the prime factors that the two numbers have in common
60 = 2 × 2 × 3 × 5
84 = 2 × 2 × 3 × 7
The common factors are: 2 and 3
GCF = 2 × 2 ×3
GCF = 12
Factor out 12 from the equation
12(5x - 7)
