1. ∠ADC is right angle, then 
2. Angles ADB and BDC are complementary, then

3. You know that ∠BDC is 32° greater than ∠ ADB. Let
then 
Since
you have that

This gives you:
Answer: 22 1/2, or 22.5
Step-by-step explanation:
1/4c + 3d
1/4(6) + 3(7)
6/4 + 21
22 2/4
22 1/2, or 22.5
Perimeter of a rectangle = 2(l + w)
l = length.
w = width
In this problem,
Perimeter = 40
w = 6
l = ?
Plug our numbers in.
40 = 2(l + 6).
Divide each side by 2.
20 = l + 6.
Subtract 6 from both sides.
14 = l
The length is 14 inches
Answer:
B) {(−2, −3), (−3, −2), (2, 3), (3, 2)}
Step-by-step explanation:
For a relation to be a function, every x value must have only one y value. For a, c, and d, some of the x values have multiple different y values
