Find the length of the unknown leg of the right triangle.

Step-by-step explanation:

a² + b² = c²

side1² + side2²  = hypotenuse²      side 1 = 6.75       hypotenuse = 11.25

                                                        solve for     side 2 = ???

side2²  =  hypotenuse²  -  side1²

side2  =  

          = √(11.25² - 6.75²)

          = √(126.56 - 45.56)

          = √(81)

side 2 = 9

x=-91/1840

Step-by-step explanation:

Firstly deal with the bracket

2(x+4-21x-5)

2(x-21x+4-5)

2(-20x-1)

-40x-2

Back to the question

1/-40x-2=46

Cross multiply

46(-40x-2)=1

-1840x-92=1

Add 92 to both sides

-1840x=91

Divide both sides by-1840

x=-91/1840
