x = 2√5 or 4.5

Step-by-step explanation:

Recall the leg rule which is given as:

Hypotenuse/leg = leg/part

Hypotenuse = 8 + 2 = 10

Leg = x

Part = 2

Plug in the values

10/x = x/2

Cross multiply

x*x = 10*2

x² = 20

Take the square root of both sides

√x² = √20

x = √(4*5)

x = 2√5 or 4.5

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

well the answer to that is xoxoxo
