Answer: If ∠P and ∠Q are complementary angles, that means they add up to 90°. If we know that ∠Q is 66°, we can use that information to find ∠P.
We can start by using the fact that ∠P and ∠Q are complementary to write an equation:
∠P + ∠Q = 90°
We know that ∠Q is 66°, so we can substitute that into the equation:
∠P + 66° = 90°
Now we can solve for ∠P by subtracting 66° from both sides of the equation:
∠P = 90° - 66°
∠P = 24°
So the measure of ∠P is 24°.
