Answer:
x = 45
Step-by-step explanation:
The angles with (2x + 45) and x are supplementary angles, meaning they add up to 180°. We can write this statement as an algebraic equation of
and solve it.
Step 1: Combine like terms.
Step 2: Subtract 45 from both sides.
Step 3: Divide both sides by 3.
Step 4: Check if solution is correct.
Therefore, x = 45.
