Question

Can someone help me figure this out?

Answer 1

what's your question?

Answer 2

first of all, do you know the rules for 45, 45 and 60,30 degree triangles?

Answer 3

Yes I do, I just don't fully understand how to work out the problem. I guessed that x=15

Answer 4

yes, x = 15

So, what does that mean for the purple triangle?

Answer 5

Uhm... I have no clue...

Answer 6

I'll give you a hint

15^2 + 15^2 = h^2

Answer 7

Can you solve for h?

Answer 8

125?

Answer 9

15^2 = 225

15^2 + 15^2 = 450

450 = h^2

h = 15squareroot(2)

do you follow?

Answer 10

OHHHHHH I GET IT yes yes I do.

Answer 11

okay, so can you figure out what y is?

Answer 12

y=h right?

Answer 13

yes

Answer 14

y=the squareroot of 15?

Answer 15

Not quite.

the side opposite the 30 degree angle in the green triangle is xsqrt(3) and we know it's equal to 15

xsqrt(3) = 15

x = 5squareroot(3)

1/2h = 5sqrt(3)

h = ????

Answer 16

Do you understand how we got to this point?

Answer 17

Yes, thank you for helping me (: I got the answer checked by my teacher and she said 100%

Answer 18

of the answers were correct
