Question

@kevin @will.h @atsie

Answer 1

This is EXACTLY like the last one that @Will.H did for oyu
except you need to use
cos 48 = c/51 (adjacent /hypotenuse)

Answer 2

How do I do that?
Idk trig formulas could you explain how exactly to use them?

Answer 3

There is no other way to solve this, except by drawing it accurately

Answer 4

I'm super sorry to be such a letdown @NvidiaIntely But I'm actually really awful at this kind of math. To be entirely honest, I'm starting my entire first math course of high school over completely this year which I already did last year and I'm supposed to be going into 11th grade.
So as of now, I think I'd misguide you entirely and I don't want to do that. I'm really sorry again. :/

Answer 5

use your calculator to find the value of cos 48°

THEN
\[\cos (48) = \frac{ c }{ 51 }\]

Answer 6

Cross multiply and that's all

Answer 7

keep the following rules in mind of trig functions

Sin x = opposite/hypotenuse

Cos x = adjacent/hypotenuse

Tan x = opposite/adjacent

SOH CAH TOA

anyways after doing cross multiply you should have an equation and to be able to solve for c

Answer 8

questions?

Answer 9

how do you multiply cos 48 * 51?

I know it's not the same as 48 * 51, right?

Answer 10

cos(48) is just a number

use your calculator to find it

Answer 11

yes the value of cos48) is 0.669130

Answer 12

I think I get it now, thanks Will!

Answer 13

Oh ok, so I find that value on a calculator by putting 48 and then clicking on cos.

Answer 14

you welcome Nv

Did it work quickstudent? usually you 1st press on cos and then enter the desired value

Answer 15

She's using Windows 8 Home :P

Answer 16

Oh well, that's how my calculator works. I got the right answer:)

Answer 17

Great!
C you guys

Answer 18

Thanks!
