Question

Questions 23 and 24 refer to the isosceles trapezoid given below.

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

so z is 65 how can i find w?

Answer 5

we're getting there

Answer 6

oh

Answer 7

i think i have to find all sides of teh triangle first

so can you get B?

Answer 8

no im really stupped :(

Answer 9

what if you have a right triangle,

can you work out the other sides?

Answer 10

ummm yes

Answer 11

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.

Answer 12

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

Answer 13

abby?

Answer 14

have you figured out the rest of the question?

Answer 15

oh sorry went to the restroom

Answer 16

oh sorry

Answer 17

i dont have a calc

Answer 18

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

Answer 19

so turns out the bottom of that new triangle is 4 in

so w = 21+4+4
=29
