Question

∠1 and ∠2 are complementary angles. ∠1 measures 70° . What is the measure of ∠2 ?

Answer 1

The sum of complementary angles is always 90 degrees. Since ∠1 and ∠2 are complementary angles, ∠1 + ∠2 = 90°. Given that ∠1 measures 70°, we can substitute that into the equation: 70° + ∠2 = 90°. Subtracting 70 from both sides of the equation gives ∠2 = 90° - 70° = <<90-70=20>>20°. Therefore, the measure of ∠2 is 20 degrees.
