Find x using the picture below.

  X = 60

Step-by-step explanation:

Considering that the radius of the circle is 11 ( a ), we need to add that to 50  in order to get the full hypotenuse ( c ).

Using the Pythagorean theorem, " a^2 + b^2 = c^2 ", we can substitute our given variables.

The result would be ( 11 )^2 + b^2 = ( 61 )^2  

                              or  ( 121 ) + b^2 = ( 3721 )

Subtract a from both sides to get b^2 = 3600

And finally, square root our answer to get b = 60

Since b is x on our chart, the answer will be x = 60

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

answer: sine
