Question

∠1 and ∠2 are complementary angles. given (mangle1 = 12^{circ}), find (mangle2). (mangle2=square^{circ})

Explanation:

Step1: Recall complementary - angle property

Complementary angles add up to 90°. So, \(m\angle1 + m\angle2=90^{\circ}\).

Step2: Solve for \(m\angle2\)

We know \(m\angle1 = 12^{\circ}\), then \(m\angle2=90^{\circ}-m\angle1\). Substitute \(m\angle1 = 12^{\circ}\) into the formula: \(m\angle2 = 90 - 12\).
