Question

find missing angles quick check there are two complementary angles, ∠5 and ∠6. if ( mangle5 = 39^circ ), what equation can you write to solve for ( mangle6 )? (1 point) ( mangle6 = 39^circ ) ( mangle6 + 39^circ = 180^circ ) ( mangle6 = 180^circ - 39^circ ) ( mangle6 + 39^circ = 90^circ )

Explanation:

Step1: Recall complementary angles rule

Complementary angles sum to $90^\circ$.

Step2: Set up the equation

$m\angle 6 + 39^\circ = 90^\circ$

Answer:

$\boldsymbol{m\angle 6 + 39^\circ = 90^\circ}$
