Question

2 find the angle measure.
$\angle3$ and $\angle4$ are complementary angles, and $m\angle3 = 46^\circ$. find $m\angle4$.
$m\angle4 = \square$

Explanation:

Step1: Recall complementary angles rule

Complementary angles sum to $90^\circ$, so $m\angle3 + m\angle4 = 90^\circ$.

Step2: Substitute known angle value

Substitute $m\angle3 = 46^\circ$: $46^\circ + m\angle4 = 90^\circ$.

Step3: Solve for $m\angle4$

$m\angle4 = 90^\circ - 46^\circ$

Answer:

$44^\circ$
