What is the area of a trapezoid abcd with bases ab and cd, if: ab = 10 cm, bc=da=13 cm, cd=20 cm?

I believe the answer is 180...

hopefully you can still use this answer

sorry about being 6 days late

i dont understand

step-by-step explanation:

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
