In the figure below, the length of line segment CB is 58 units and the length of line segment BG is 120 units. What is the length of line segment GE?

Does anyone know a formula I would use to solve this

1......find AB using tan 45 in triangle ABC 2......find AG using AG=120AB 3......find GE using tan 60 in triangle AGE o.O

Doesn't tan(45) = 1?

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

Remember how the legs of a 454590 triangle are the same length? Can you find AG knowing that?

I just used the ratio for a 454590 triangle and 306090 triangle.

Oh. You misread that part for AG....it said 120  x. When I said to figure out the rest, I meant did you understand how to get the answer now using the ratios, but it's good practice XD Good job by the way :)

If you didn't notice, all it asked for was GE which you have as 62√3 which you have :)

Yup :) Good work! That one part on the bottom of the 306090 triangle is wrong because you misread it, but as long as you understand the concept, it's fine :)

Yeah. I think you read it as 20  x when it's 120  x.

Good job though. 454590 and 306090 triangles can be very simple once you remember the ratios! :D
