Find $m \angle A$ if $m \angle B=17^{\circ}$ and $\angle A$ and $\angle B$ are complementary.
Added by Stephen S.
Step 1
So, we can write the equation: $m \angle A + m \angle B = 90^{\circ}$ We are given that $m \angle B = 17^{\circ}$. Now we can substitute this value into the equation: $m \angle A + 17^{\circ} = 90^{\circ}$ Show more…
