Arigjt triangle with two congruent legs is always 45-45-90

right angel triangle means one of the three angel is 90

also it is given that two sides are equal

there for it is an isoselas triangle means other two triangles are equal

let the other two angels be x then

then 90 + x + x = 180

2x = 180 - 90

x = 90 ÷2

× = 45

prof. 90 + 45 + 45 = 180

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)
