A. Write an equation that would help you solve for the missing angle measurements by light terms. Remember the triangle sum theorem. B. Saw the equation to find the value of X show/explain all your steps using inverse operations

1 answer

A. Let the missing angle measurements be represented by x, y, and z. According to the triangle sum theorem, the sum of the interior angles of a triangle is 180 degrees. Therefore, we can write the equation:

x + y + z = 180

B. Now, let's solve for the value of x using inverse operations.

Given: x + 45 + 75 = 180

Combine like terms:

x + 120 = 180

Subtract 120 from both sides:

x = 60

Therefore, the missing angle measurement is 60 degrees.
