MATH PROBLEM 5 STARS!!

[From: ] [author: ] [Date: 11-10-10] [Hit: ]
Heres one way to solve it.H = 4/sin60 = 4/(sqrt(3)/2) = 8/sqrt(3) = 8sqrt(3)/3 or about 4.62.Lord bless you today!......
I have a triangle with an angle of 60 and opposite side of 4.
I am trying to find the hypotaneuse so I use tangent.
Sin= opposite divided by hypotaneuse.
Sin60=4/H
H=4xSin60
H=3.46

I know the answer is wrong but how do I do it right.
I will give 5 stars to a verry detail answers :)

its your rearanging where you have gone wrong

use sin like you said.

sin = o/h
sin60 = 4/h
h = 4/sin60
h = 4.62 aprox

-
The sine - cosine - tangent solution can only be applied to a right triangle. Is your triangle a right triangle? If so:

Sin 60 = 4 / H

H = 4 / sin 60

H = 4.6188 ----> You wrote the equation wrong, it's h = 4/ sin 60

Why? Because H is dividing, so it goes to the other side multiplying. Then, sin 60 is multiplying, so it goes to the other side dividing 4
:)

I'm assuming this is a right triangle since the hypotenuse is mentioned in the problem.
Your equation Sin60=4/H is correct, but you did not solve the equation correctly.
Here's one way to solve it.

Sin60/1=4/H
H*sin60 = 1*4
H = 4/sin60 = 4/(sqrt(3)/2) = 8/sqrt(3) = 8sqrt(3)/3 or about 4.62.

Lord bless you today!
