Answer:
162
Step-by-step explanation:
Note that you can split the given shape into a triangle and a rectangle.
Area of rectangle = base x height
base = 12
height = 9
Plug in the corresponding numbers into the corresponding variables:
Area of rectangle = 12 x 9
= 108
Area of triangle = (base x height)/2
base = 12
height = 9
Area of triangle = (12 x 9)/2
= (108)/2
= 54
Next, add the two areas together to get the full area:
108 + 54 = 162
162 is your answer.

Answer:
72°
Step-by-step explanation:
Hello There!
Complementary angles have a sum of 90 degrees
So to find the missing angle we subtract the measure of the given angle (18 in this case) from 90
90 - 18 = 72
so your answer will be 72°
