You'll use the sine trig function because we want to tie together the known opposite side (10) and the unknown hypotenuse (x). 

sin(angle) = opposite/hypotenuse
sin(55) = 10/x
x*sin(55) = 10
x = 10/sin(55)
x = 12.2077 ... make sure your calculator is in degree mode
x = 12.2

Answer: Choice A

What value of x makes the equation 3(x-6) -8x= -2+5(2x+1
Nutka1998 [239]

Answer:

x = -7/5

Step-by-step explanation:

3(x-6) -8x= -2+5(2x+1)

Distribute

3x -18 -8x = -2 +10x +5

Combine like terms

-5x -18 = 3 +10x

Add 5x to each side

-5x+5x-18 = 3+10x+5x

-18 = 3+15x

Subtract 3 from each side

-18-3 = -3+3+15x

-21 =15x

Divide each side by 15

-21/15 = 15x/15

-7/5 = x
