Side A is 128 degrees.

Question

Side B is (X - 61) degrees.

Solve for x

Answer 1

To solve for X, we can add the two angles to obtain the total angle measure of the triangle:

128 + (X - 61) = 180

Combine like terms:

X + 67 = 180

Subtract 67 from both sides to isolate X:

X = 113

Therefore, X is 113 degrees.
