Question

Use the relationship between the angles in the figure to answer the question.

Which equation can be used to find the value of x?

Drag and drop the equation into the box.

Answer 1

First you have to add 31 and 40=71
Then you do 180-71=109
X=180-(31+40)

Answer 2

x = 180 - 31 + 40

Explanation:

bc one straight line is 180° so to find x you must add the numbers given which in this case are 40° and 31° and subtract 180°

x = 180°- 31° + 40°

= 180°- 71°

= 109°

so the value of x is 109°
