The sum of two complementary angles is always 90 degrees. So, in this case, we can write the equation:
m∠5 + m∠6 = 90°
Since we know that m∠5 is 39 degrees, we can substitute it into the equation:
39° + m∠6 = 90°
There are two complementary angles, ∠5 and ∠6 . If m∠5=39° , what equation can you write to solve for m∠6 ?
