Triss [41]

Answer:

16.4 feet

Step-by-step explanation:

For a right triangle

sin(x) = \frac{opposite}{hypotenuse}

Since we know the angle and the hypotenuse, we can calculate the opposite side.

\sin(66)=\frac{x}{18}

Multiply each side by 18

18sin(66)=x

x=18sin(66)  

Calculate sin(66)

sin(66)=0.914

18*0.194=16.4

nikdorinn [45]

Answer:

-5/4

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

   = ( -3 -2)/( 3 - -1)

   = ( -3-2 ) /( 3+1)

   = -5/4

I require assistance with this problem.<br> Solve for X:<br> 5/10 + 1/x = 5/6
BabaBlast [244]

Answer:

x = 3

Step-by-step explanation:

Solve for x:

1/2 + 1/x = 5/6

Bring 1/2 + 1/x together using the common denominator 2 x:

(x + 2)/(2 x) = 5/6

Cross multiply:

6 (x + 2) = 10 x

Expand out terms of the left hand side:

6 x + 12 = 10 x

Subtract 10 x + 12 from both sides:

-4 x = -12

Divide both sides by -4:

Answer:  x = 3
