Answer:
9cm
Step-by-step explanation:
Area of trapezium=(1/2)×(a+b)h
A=33
a=2
b=?
h=6
(1/2)(2+b)(6)=33
(1/2)(12+6b)=33
6+3b=33
3b=33-6
3b=27
b=27÷3
b=9
Answer:
I'm pretty sure it's 6(x+8)=60

Answer: D) Midsegment Theorem for Trapezoids</h3>
Assuming that the bottom horizontal segment is 9 units long, this would mean that x = 5 on top, added to the 9 on the bottom, gives 5+9 = 14. This cuts in half to get 14/2 = 7, which is the length of the midsegment of the trapezoid.
In short: add the parallel sides of the trapezoid, then cut that result in half. This will yield the midsegment.
