Answer:
x° = 125°
(x+10)° = 135°
Explanation:
Given:
Sum of measures of angle = 720°
Solution:
We know that:
Sum of measures of angle = 720°
120 + 100 + 120 + x + 10 + 120 + x = 720
x + x + 120 + 100 + 120 + 10 + 120 = 720
2x + 470 = 720
2x = 720 - 470
2x = 250
Divide both sides by 2
x = 250/2
x = 125
Now,
Angles measures
x° = 125°
(x+10)° = (125+10)° = 135°
