What is the value of m∠1 to be if ∠1 and ∠2 are complementary angles and m∠2 = 85?

1 answer

Complementary angles add up to 90 degrees. If m∠2 = 85, then m∠1 + m∠2 = 90.

Substituting m∠2 = 85 into the equation:
m∠1 + 85 = 90

To solve for m∠1, subtract 85 from both sides:
m∠1 = 90 - 85

m∠1 = 5

Therefore, the value of m∠1 is 5 degrees.
