Answer:
yes, because they are side to side
Step-by-step explanation:
Supplementary angles must equal 180.
So to figure out the angle supplement take 180 - 63 = 117
The supplement angle is 117
question 5
Complementary angles must equal 90
So to figure out the angle complement take 90 -51 = 39
The complement angle is 39
The answer is 5x-11
You have to distrivute 1/3 into 6x and -9 and after you have your answer for those you can combine like terms.
Answer:
x = 16
Step-by-step explanation:
If the figure is a parallelogram, the opposite sides are the same length
3x+20 = 5x-12
Subtract 3x from each side
3x+20 -3x = 5x-12-3x
20 = 2x-12
Add 12 to each side
20+12 = 2x-12+12
32 = 2x
Divide each side by 2
32/2 = 2x/2
16 =x
