Question

Think carefully about the angle relationship the following represents.

What is the value of ∠JML?

Answer 1

Angles are supplementary hence their sum is 180°

• 3x+54=180
• 3x=180-54=126
• x=126/3
• x=42

So

<JML=3x=126°

Answer 2

<JML=126 degrees, x=42

Explanation:

well, something important to note here is that a straight line is allways equal to 180, and you have part of the 180 sitting there on the line being 54 degrees, so all you have to do is do 180-54=126 and that is the measure of <JML, to find x, you just reverse the steps you see, right now 3x=3*x so you want to reverse that and divide 126/3=42.
