Answer:
90 degrees
Step-by-step explanation:
All trapazoids are equal to 360 degrees.
so we can make an equation 2x+x+x=360 (the other corner would also be x because its an unknown value)
to simplify, 4x=360
you divide into both sides (360/4)
you get 90
Answer:
The answer is -2.
Step-by-step explanation:
This is because if you plug in any number for x, they will always equal each other.
Subtitute the pair (3,28) to x and y, if the result in right side is -8, then the pair is a solution to the equation
2x - y/2
= 2(3) - 28/2
= 6 - 14
= -8
The result is -8, so the pair (3,28) is a solution
