Question

Solve for x. show work please!! 30 points <3

Answer 1

Explanation:

We know that the sum of all angles of a triangle is 180 °.

x + 45 + x + 64 + 79 ° = 180 °.

combine like terms

x + x + 64 + 45 + 79 ° = 180 °

2 x + 188 ° = 180 °

Subtract

2 x = 180 ° - 188 °

2 x = - 8 °

Divide

x = -8 ° / 2

x = - 4 °

x + 45 = - 4° + 45 ° = 41°

x + 64 = - 4° + 64 ° = 60 °

Answer 2

Explanation:

Sum of all angles of a triangle = 180

x + 64 + x + 45 + 79 = 180

Combine like terms.

2x + 188 = 180

2x = 180 - 188

2x = - 8

x = -8/2

x = -4

x + 64 = -4 + 64 = 60

x + 45 = -4 + 45 = 41
