Question

Please help!!!
Solve for x and I need help setting up the equation and solving it!!

Answer 1

-4

Explanation:

The total degree of a triangle is always 180.

20 + 140 + 24 + x = 180

now we simplify and relocate some numbers to the other side of the equal sign.

20 + 140 = 160

160 + 24 + x = 180

24 + x = 180 - 160

24 + x = 20

x = 20 - 24

x = -4

check

20 + 140 + -4 + 24 = 180

Answer 2

x = - 4

Explanation:

Sum of interior angles in a triangle = 180

so

x + 24 + 20 + 140 = 180

x + 184 = 180

x = - 4
