Question

Find the value of x. Then find the angle measures of the polygon.

Answer 1

Answer:

120+100+120+120+x+x+10=720 (given)

470+2x=720

2x=720-470

x=250/2

x=125

           

Step-by-step explanation:

Answer 2

Answer:

x° = 125°

(x+10)° = 135°

Step-by-step 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°

$\rule[225]{225}{2}$
