\sin B is the ratio of the length of the leg opposite angle B to the length of the hypotenuse:

\sin B=\dfrac{21}{29}

It will be the same as \cos A, which is the ratio of the length of the leg adjacent to angle A to the lenght of the hypotenuse.

Solve the equation 2x+8=12+10x
kari74 [83]

Solve the equation. Isolate the variable, x.

Note the equal sign, what you do to one side, you do to the other.

First, subtract 8 and 10x from both sides:

2x (-10x) + 8 (-8) = 12 (-8) + 10x (-10x)

2x - 10x = 12 - 8

Simplify. Combine like terms:

(2x - 10x) = (12 - 8)

-8x = 4

Isolate the variable, x. Divide -8 from both sides:

(-8x)/-8 = (4)/-8

x = -(4/8)

Simplify:

x = -1/2

-1/2 is your answer for x.
