Question

What are the measures of the two angles in the figure? A. 125° and 55° B. 120° and 60° C. 100° and 80° D. 92° and 88°

Answer 1

Explanation:

1. Know that the sum of angle A & B equal 180°
2. In order to find the measures you must find X.
3. Plug X's value into the equations for angle A and B
4. both should equal 180°

Answer 2

Step-by-step explanation: You would do 5x+20+x+40=180

Then you would add 5x and x together and you would also add 20 and 40 together and then you get: 6x+60=180

You would then subtract 180-60 and then you should get 6x=120 and the you would divide from both sides and you should get x=20 you would then plug it into both angles So 5(20)+20 and you should get 120 for the left angle and then you would do the next angle which would be 20+40=60 for the right angle

Short version:

5x+20+x+40=180

6x+60=180

6x=120

X=20
