The sum of a trapezoid is 360 degrees
45+90+90+x=360
45+180+x=360
225+x=360
x=135
Answer:
-3
Step-by-step explanation:
First take (-3+2) and simplify that which will turn into (-1). Then take (-5+7) which will turn into (2). Then plug that back into the equation and you get (-1)-(2). And you get -3.
Answer: x = 2, y = 9
Step-by-step explanation:
y = 9x - 9 Substitute x for 2
y = 9(2) - 9 Multiply 9 with 2
y = 18 - 9 Subtract 18 - 9
Final Answer: y = 9 and x = 2
