Question

geometry help!

Answer 1

crapp, i thought it'd be easy stuff.

Answer 2

but i can still help: studied trig in 6th

Answer 3

1. the last one, i think

Answer 4

2. is the second one, i think too

Answer 5

:D

Answer 6

not 100% sure, but pretty sure

Answer 7

like 98%

Answer 8

someone school me plz i need halp

Answer 9

No. 1. Is wrong.
Use the pythagoereom theorem. a^2 +b^2 =c^2
Where a and b are the legs of the right triangle
And c is the hypotenuse
You know one of the leg is 18 and the hypotenuse is 21
So
18^2 + b^2 =21^2
Can you solve for b?

Answer 10

it'd have to be the square root of something

Answer 11

117

Answer 12

but how would you convert that into a square root?

Answer 13

first is A then?

Answer 14

Sqrt of 117
You know 117=9x13
And 9 is a perfect square because 3^2=9 or sqrt9=3
So
Sqrt117= 3 sqrt 13

Answer 15

how do i solve the second one?

Answer 16

yeah
i will try to get the second one

Answer 17

Have you learned about the similarities in a right triangle?
And with that you have
The altitude is the geometric mean of the segments into which it separates the hypothenuse

Answer 18

In other words, if we were to use you diagram, it'll be

GI= sqrt (FI x IH)

Just to let you know, everything on the right side is under the radical sign

Answer 19

Nikato, if you find yourself having trouble explaining, I'd be willing to assist.

Answer 20

would it also be A too? I solved it and 8.4

Answer 21

Yes. It would also be A. But I think I would best it you leave your answers in radical form

Answer 22

oh ok.. thank you for your help!

Answer 23

your welcome!

Answer 24

you did way better than i did... i kind suck at this kinda stuff...
