OpenStudy (anonymous):

right, well ill just continue here.. remember the properties of an isosceles trapeszoid.

OpenStudy (anonymous):

so from that you have internal angles ( x=115, y = 65, z=65

OpenStudy (anonymous):

you can also draw lines straight down from E and F and work out A and B 37-21 = 16 16/2 = 8 so now point H to directly below E is 8 and point G to directly below F is 8 too

OpenStudy (bbb911):

so z is 65 how can i find w?

OpenStudy (anonymous):

we're getting there

OpenStudy (bbb911):

oh

OpenStudy (anonymous):

i think i have to find all sides of teh triangle first so can you get B?

OpenStudy (bbb911):

no im really stupped :(

OpenStudy (anonymous):

what if you have a right triangle, can you work out the other sides?

OpenStudy (bbb911):

ummm yes

OpenStudy (anonymous):

its the same triangle as the one in the isosceles ... so once you get the hypotenuse of that triangle, you have A and B in your question.

OpenStudy (anonymous):

do it please, cause i dont have a calculator...

OpenStudy (anonymous):

abby?

OpenStudy (anonymous):

have you figured out the rest of the question?

OpenStudy (bbb911):

oh sorry went to the restroom

OpenStudy (anonymous):

oh sorry

OpenStudy (bbb911):

i dont have a calc

OpenStudy (anonymous):

doesn't mattehr, i found one online make the points directly below E and F points e and f E to e is 3.73 F to f is 3.73 A and B are 8.83 point w on E-e is half way so 3.73/2 = 1.865 now you just do the same kind of calculation but with a smaller triangle attached

OpenStudy (anonymous):

so turns out the bottom of that new triangle is 4 in so w = 21+4+4 =29

Thank you so much paul
