Question

Please help!!! What is the value of x? http://static.k12.com/calms_media/media/1422500_1423000/1422767/1/52235abcda5a63ec3d6e60069a91f82606ac9fe4/MS_PA_131002_171216.jpg
A:4
B:4√3
C:8
D:8√3

Answer 1

forgot ur trig? x is the opposite, 16 is the hypotenuse...

Answer 2

hint: sin (theta) = opposite / hypotenuse

Answer 3

I still don't understand, I have read the lesson 5 times now but I cant figure out how to solve this.

Answer 4

remember this formula, it'll make every single problem like this EASY AS PIE, here it is: SOH-CAH-TOA, easy to pronounce, it stands for Sine-Opposite-Hypotenuse, Cosine-Adjacent-Hypotenuse, and Tangent-Opposite-Adjacent

Answer 5

now, by looking at the given figure, u can easily tell which 2 sides are given, are they hypotenuse? adjacent? or opposite? u can tell by looking at it. after that, just use SOH CAH TOA and ur calculator :D

Answer 6

by the way, hypotenuse, adjacent and opposite is with respect to the angle

Answer 7

But only one side is given??

Answer 8

x is also a side! it's opposite of the angle isn't it?

Answer 9

that's what ur solving for

Answer 10

but what about the bottom side?

Answer 11

u don't need the bottom side, all u need is 2 of the sides, so either OH, AH or OA wud work. each corresponds to a different trig function (sin, cos, or tan), and that's the function u have to use to solve the problem

Answer 12

Soo 16^2 will give me the correct answer?

Answer 13

where did the 2 come from?...here lemme draw out the problem
