Hello there! :D
Find the scale of the sides.
40/5=8 (the longer side is 8 times bigger than the shorter one)
3*8= 24
2x+10=24
Subtract 10 on both sides.
2x=14
Divide by two on both sides.
x=7
I hope this helps!

Number 5 would be D i think
Answer: D. 50
Step-by-step explanation:
the sum of opposite angles of a cyclic quadrilateral are always 180 degrees
80 +2x= 180
2x= 180 - 80
x= 100/2
x= 50
Answer:
18 units^2
Step-by-step explanation:
Formula for Area of trapezoid: ( base 1 + base 2 / 2) * height
(3 + 9 / 2) * 3 = (12 / 2) * 3 = 6 * 3 = 18 units^2
I hope this helps
