Question

Can anyone please solve for x?

Answer 1

Answer:

-3

Step-by-step explanation:

If x + 74 represents the last angle, then it would be -3 as:

a triangle has 180 degrees

55 + 54 = 109

109 + 74 = 183

183 degrees is 3 over the degrees in a triangle, so you subtract 3 from it to make 180

183 - 3 = 180

idk if that's what its asking for though

Answer 2

Answer:

x = -3

Step-by-step explanation:

The sum of the angles of a triangle is 180 degrees

55+54 + x+74 = 180

Combine like terms

183 +x = 180

Subtract 183 from each side

183-183 +x = 180-183

x = -3
