Find ∠CAD in a Right Triangle with 61° and 17° Angles

If we look at triangle ABD, we can see that we are given two angles: 90° and 17°.

Since the sum of all angles in a triangle equals 180°, we can calculate angle BAD as follows:

$180-90-17=73$

Since we know angle BAC, we can calculate angle CAD as follows:

$73-61=12$
