Question

Solve for x to the nearest degree.




Answer 56 degrees
34 degrees
50 degrees
40 degrees

Answer 1

do you know SOH CAH TOA?

Answer 2

no

Answer 3

id explain but i suggest you google it real fast
it will help a LOT with trig

Answer 4

it is about trignometry dear chirs parks!!!

Answer 5

you are given the opposite side and hypotenuse so you need SOH
sine = opp/hypot

Answer 6

ok you guys my google is messing uhp can someone explain this to me

Answer 7

sin x = opposite/hypotenuse
cosx= adjacent/hypotenuse
tanx= opposite/ adjacent

here u hav the angle x and u hav the hypotenuse and the opposite side of the angle,
so u write sin x= opposite/hypotenuse =15/18=5/6
so sin inverse of (5/6) = 56.44
so x= 56.44

Answer 8

SOH CAH TOA is an aid to memory
sine = opposite side /hypotenuse
cosine = adjacent/ hypotenuse
tangent = opposite / adjacent

hypotenuse = longest (slanting) side
opposite = side opposite the angle you are considering
adjacent = other side ( the side the angle is 'sitting' on)

(these rules are only true for a right-angled triangle)

Answer 9

thnk you because i have never heard of that before

Answer 10

its very handy - sounds a bit like hawaain

Answer 11

use wolframalpha.com to solve pretty much any math issue. heres the section on trig: http://www.wolframalpha.com/input/?i=trig


Also the answer is: 56.442690238079284707119200844376

Answer 12

in your problem opposite side (O) = 15 and hypotenuse (H)= 18
so you have OH - so you use the sine

sine x = 15/18

so x is the angles whose sine is 15/18 (or 0.83333..)
if you haVE A SCIENTIFIC calculator press sin-1 followed by 0.83333 and it will g
deliver the value of angle x
