Can anybody help me solve this? You must solve for x first.

ABC = 65

Step-by-step explanation:

The sum of the angles of a quadrilateral are 360

2x-15 + x + 2x-15 +x = 360

Combine like terms

6x -30 = 360

Add 30 to each side

6x -30 +30 = 360+30

6x= 390

Divide by 6

6x/6 = 390/6

x=65

We want angle ABC

ABC = x

ABC = 65

The measure of angle ABC is  65 degrees.

Step-by-step explanation:

2x- 15 + 2x - 15 + x + x =360

6x  - 30 = 360

      + 30    + 30

6x = 390

x= 65

check:   2(65) - 15 = 115

115 + 115 + 65 + 65 = 360

it would more likely be bald eagle because its has more in the box so about 75%.
