Answer:

60 degrees

Step-by-step explanation:

CAD and CAB are <em>complementary </em>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!

Answer:

60 degrees

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

Step-by-step explanation:

Hello!

For this problem we are given that quadrilateral ABCD is congruent to quadrilateral GJIH, meaning that all sides and angle measures will be equivalent to its corresponding side.

This means that to find $x$ , we can look at quadrilateral GJIH's corresponding side to quadrilateral ABCD's side AD, which is side GH, which has a value of 9.
