Question

how are ∠1 and ∠2 related?
complete the equation.
m∠1 + m∠2 = 90 °
when the measures of two angles sum to 90°, they are complementary. ∠1 and ∠2 are complementary angles.
m∠1 = 55°. what is m∠2?
m∠2 = °
m∠1 + m∠2 = 90°

Explanation:

Step1: Use complementary angle formula

$m\angle1 + m\angle2 = 90^\circ$

Step2: Substitute $m\angle1 = 55^\circ$

$55^\circ + m\angle2 = 90^\circ$

Step3: Solve for $m\angle2$

$m\angle2 = 90^\circ - 55^\circ = 35^\circ$

Answer:

35
