Last one
Because you have to substitute it
So you do X times 2 - 16 = 0
And the only X that works is the last one cause 8 X 2 = 16 and 16 -16=0
The true answer is A. all parallelograms are rectangles
Solve for y
minus 10x from both sides
5y<-10x+15
divide both sides by 5
y<-2x+3
Answer:
x = 21°
Step-by-step explanation:
Vertical angles have the same measures, therefore:
3x - 30 = 2x - 9
x - 30 = -9
x = 21°
