The answer is 14 m

<span>In a 30°-60°-90° triangle, the hypotenuse (c) is twice the length of the shorter leg (a) which is the opposite to the 30 angle:
</span>

c = 2a


We have c = 28 m

So: 28 = 2a

      a = 28 / 2 

     a = 14 m

To find the length of the opposite side you just have to use the formula
Sin 30° = opposite side / hypotenuse length
You Cross Multiply and you get
opposite side = Sin 30° x hypotenuse length opposite side length= 1/2 x 28 = 28/2
Opposite side length = 14.

Hope you will understand it.

K=am+3mx solve for m
Otrada [13]
Assuming the variables are constants, you isolate m. So move am to the left. K-am=emx. Now divide ex. This gives you, m=(K-am/ex)
