Question

find the measure of the missing angle.
answer
a = \boxed{}

Explanation:

Step1: Use the property of complementary angles

Complementary angles add up to \(90^{\circ}\). Let the missing angle be \(a\). We know that \(a + 57^{\circ}=90^{\circ}\).

Step2: Solve for \(a\)

Subtract \(57^{\circ}\) from \(90^{\circ}\), so \(a = 90^{\circ}-57^{\circ}\).

Answer:

\(33^{\circ}\)
