Two geometry questions! double the points in advance!

2x-4+50=100

2x-4=50

2x=54

x=27º

2x+4x=90

6x=90

x=15º

1. Simplify 100 = (2x - 4) + 50

x = 27

2. Complementary mean the angles equal 90 degrees when added, so

90  = 2x + 4x

x = 15

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

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)
