Question

1 find the angle measure. ∠1 and ∠2 are complementary angles, and $m∠1 = 23°$. find $m∠2$. $m∠2 = \square$°

Explanation:

Step1: Recall complementary angle rule

Complementary angles sum to $90^\circ$, so $m\angle1 + m\angle2 = 90^\circ$.

Step2: Substitute known angle value

Substitute $m\angle1=23^\circ$: $23^\circ + m\angle2 = 90^\circ$.

Step3: Solve for $m\angle2$

Rearrange to isolate $m\angle2$: $m\angle2 = 90^\circ - 23^\circ$.

Step4: Calculate the result

Compute the difference: $m\angle2 = 67^\circ$.

Answer:

$67$
