ABCD is a rectangle. Find the measure of angle CAD

60 degrees

Step-by-step explanation:

CAD and CAB are complementary angles, meaning that they add up to 90 degrees (and form a right angle- of course!)

Therefore, we know that the angle measure of CAB is 30 degrees and we have 30 degrees+CAD=90 degrees.

Subtracting thirty degrees from both sides of this equation we get CAD=60 degrees.

Hope this helps!

60 degrees

because you are tring to find what minus the other angle equals 90

Step-by-step explanation:

therefore since the other angle is 30

90-30=60
