Question 311667: Not sure how to explain these but here goes...
The directions are Use the Pythagorean Theorem to find the missing side. Then calculate the perimeter.
This is a trapezoid with a right angle. The top base is 30. The bottom base is 60 and the leg of the right angle is 20. I need to find X but for the life of me I do not know how. Thanks for your help if you understand.
Then this one.
Another trapezoid. Top base is 30 and bottom base is 58. The height is 50. Need to find the two legs which are each X.

Thanking you so much in advance.

Hello,
First draw out the trapezoid and drop a line straight down from the top end point to the bottom. Since we know the top is 30 then the bottom from the line dropped down to the end is 30. Now we can use the Pythagorean Theorem.
30^2+20^2=c^2 rewritten as:
900+400=c^2 Square root both sides to get:
c=36.06 rounded off
Now we can find the perimeter by adding all the sides to get:
146.06
Make sense?
See if you can do the next one.
