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

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°

Hope this helped!

25/4

step-by-step explanation:

call segment cd's length x. because dc and ab are parallel, angle acd and cab, so triangles adc and abc are similar and we can set up the equation x / ac = ac / ab, or x / 5 = 5 / 4 and x = 25/4.

36 is the final answer! : )
