Does anyone know a formula I would use to solve this

Answer 1

@ash2326

Answer 2

use sin/cos

Answer 3

to find BA , then subtract that from 120

Answer 4

to find AG

Answer 5

use trig again to find GE

Answer 6

@ . @

Answer 7

1......find AB using tan 45 in triangle ABC

2......find AG using AG=120-AB

3......find GE using tan 60 in triangle AGE

o.O

Answer 8

@rebeccaskell94 did you understand?

Answer 9

Idunnow

is mukushala and 91's ways good? how do you do sin/cos anyway D: urg I'm so confused. My brain is not a math brain :(

Answer 10

I triangle CBA, what's tan 45? @rebeccaskell94

Answer 11

Doesn't tan(45) = 1?

Answer 12

yeah, you;re right but it's also perpendicular/ adjacent, isn't it?

Answer 13

Idk what to do with it now D:

Answer 14

Remember how the legs of a 45-45-90 triangle are the same length? Can you find AG knowing that?

Answer 15

Are you studying trig? these are 45-45-90 triangle and 30-60-90 triangle

Answer 16

ummm can we have like, 1 person helping me xD too many is making it worse. It takes a while to help me bc my brain...it doesn't get along well with math

Answer 19

I'll let others help here :P
I'll observe silently :)

Answer 20

But ashy!! D: I wanted you to help me xD

Answer 21

If x = 58, can you figure the rest out?
