Geometry Help!!!

Answer 1

what do u need help with

Answer 2

ABCD is an isosceles trapezoid with legs AB and CD and base BC. If the length of AB is 7y - 4, the length of BC is 4y - 6 and the length of CD is 8y - 18, find the value of y.

Answer 3

what is that link for?

Answer 4

Answer 5

Like this. @ayyookyndall

Answer 6

Well there was no picture...

Answer 7

But that looks like it will work @confluxepic

Answer 8

And we have to find y.

Answer 9

@ayyookyndall
Do you know which two sides are equal.

Answer 10

Umm BC and AD? @confluxepic

Answer 11

No.BC is greater than AD.

Answer 12

Well. Now its obvious. The other two sides are equal.

Answer 13

Then AB and CD @confluxepic

Answer 14

Yes.

Answer 15

Okay so whats next?

Answer 16

So 7y-4=8y-18.

Answer 17

Can you do the rest.

Answer 18

Umm I can try... When I get it, ill let you know.

Answer 19

Ok.

Answer 20

Isosceles means that two sides are equal. In this problem, the non-parallel sides will be equal.


AB and CD are the two equal sides.

7y - 4 = 8y - 18

(Add 18 on both sides)

7y + 14 = 8y

(Subtract 7y from both sides)

14 = 1y

(Divide 1 on both sides)

14 = y

Answer 21

Correct.

Answer 22

I am so glad you know how to do math.
