The hypotenuse of a 45-45-90 triangle has a length of 10 units. what is the length of one of its legs?
Blizzard [7]

the length of a leg on a 45-45-90 triangle given the hypotenuse is half the length of the hypotenuse times sqrt(2)

hypotenuse = 10

 10/2 =5

 so the answer should be 5sqrt(2), which I don't see as a choice

What is the solution to the equation -0.2(x - 20) = 44 - x? x = -90 x = 50 x = -50 x = 90
Arturiano [62]

Answer:

x= 50

Step-by-step explanation:

First, simplify the equation

Expand the terms on the left hand side to make it easier to rearrange

   -0.2(x-20) =44-x

   -0.2x+4 =44-x

Rearrange the equation by moving the numbers to one side and the variables to the other

   -0.2x +x= 44-4

    0.8x = 40

Isolate for x

    x= 40/0.8

    x= 50
