Answer:

x=3

Step-by-step explanation:

In order to solve this kind of equation, you need to be able to understand what the question is asking. This question is asking what value of X will make both sides equivalent to each other?

<em>In order to find out, you need to get X by itself. </em>

The first step is to subtract 115 from both sides.

7x+115=136

-115  |  -115

7x=21

Now, the X value is by itself with another value on the other. With this part, you need to divide both sides by 7.

7x=21

/7 | /7

x=3

This is because you have 7 X's and you need to have only 1 of the X's.

Let me know if this was helpful or if you need any more help. Have a nice day. :)

Answer: x=5

Explanation:
sin=opposite side/hypotenuse
The opposite side is x and the hypotenuse is 10.
So your equation is: sin(30)=x/10
In order to get x by it self times ten to each side of the equation.
10 x sin(30)= x
Put 10 x sin(30) into graphing calculator and make sure your calculator is set to degrees.
