Question

Lines l and m are parallel. If m∠2 = 35 degrees and m∠3 = 4x - 13, then what is the value of x? 12 35 11/2

Answer 1

12 is the correct answer

Answer 2

x = 12

Explanation:

We use the Alternate Interior Angles Theorem to help us solve for missing degree x.

Step 1: Set up equation

m∠2 = m∠3

35° = (4x - 13)°

Step 2: Solve for x

35 + 13 = 4x - 13 + 13

48 = 4x

48/4 = 4x/4

12 = x

x = 12
