If the question is asking what 36x78 is the answer is 2,808
Answer: 
Step-by-step explanation:
Since, here the length of the rectangle is represented by the function l(x) = x + 24,
While the breadth of the rectangle is represented by the function w(x) = x + 16.
And, we know that the area of the rectangle = length of the rectangle l(x) × breadth of the rectangle.
a(x) = l(x) × w(x)
a(x) = (x + 24) × (x + 16)
AND?!?
.....................................
Supplementary means that the angles have to add up to 180, so you have your equation.
180=5x+17x-18
198=22x
x=9
Then to find the measures of the angles, you plug x back in.
m∠ABD=5(9)=45 degrees
m∠BDE=17(9)-18=153-18=135 degrees
Answer:
D
Step-by-step explanation:
We know that if angles x and y are complementary, then sin(x)=cos(y).
This means the measures of the angles have to add to 90 degrees, which is satisfied by the fourth option.
