Question

Can someone help me on this geometry problem please? *I will post the snippet on what I need help on*

Answer 1

zyx is a right triangle ?

Answer 2

Yea

Answer 3

the law of cos do you know in a right triangle ?

Answer 4

Yea. Isn't it adjacent over hypotenuse?

Answer 5

sure ,this is

Answer 6

so than cos x = ?

Answer 7

yea

Answer 8

yea what ?

cos x = ?

Answer 9

oop, I thought you was asking if I needed to find the cos of x. I think it's 9/12. Do I divide that then find the inverse cos of that to get x?

Answer 10

no

you ve wrote above the law of cos in a right triangle - so just you need use it and get the cos x value correct

Answer 11

I took 9/15 and did the inverse cos and I got 53.1301

Answer 12

where you see there 9

i see there 10 - 12 and 15

Answer 13

Here's a better image of the triangle. I was trying to snip it without getting the question number in it. This is for a study guide

Answer 14

ok so than the cos x = 9/15

Answer 15

I would then divide that and take the inverse cos to get the answer? If my thinking is correct, would I get 53.1301?

Answer 16

what you have with this inverse ? i dont see this never

you need getting the value of cos zxy = ?

Answer 17

I took the cos of 9/15 and got 0.9999

Answer 18

how you get this 0,9

9/15 = 3/5 = ?

Answer 19

so just in your had 3/5 = 0,
30/5 = 6

so 3/5 = 0,6

ok ?

Answer 20

so simply and easy

Answer 21

Thank ya

Answer 22

yw and anytime just tag me than i m online and i will try help you always

Answer 23

I'll keep that in mind :)

Answer 24

ok - bc. is my pleasure to help in math always - i relax with ...
