Answer:

They are vertical angles

x = 5

The mesure of the angles are 35, 35, 145, and 145

Explanation:

vertical angles are derectly acrost from each other.

the equations 3x+20 and 10x-15, put into the equation 3x+20=10x-15 will solve for x.

20 = 10x − 15 − 3x

20 = 7x - 15

20 + 15 = 7x

35 = 7x

35/7 = x

5 = x

x = 5

The equations solved are 3 x 5 + 20 = 35 and 10 x 5 - 15 = 35

The sum of all the angles is 360, therefore 35 + 35 = 70

360 - 70 = 290

290/2 = 145

The last two angles are 145 degrees
