25 the completed construction of a regular hexagon is shown below. explain why △acf is a 30º-60º-90º triangle. here is what i have so far, can anyone me finish this proof out? ! 1) based on the theorem of a 30°-60°-90° triangle the sides are in the ratio 1 : 2 : √3 1 → short leg 2 → hypotenuse √3 → long leg since this is a regular hexagon that means that each side is the same length. a normal hexagon equivalent and has six angles of 120° .angle f must then equal 60 degrees because it is half of the angle of the regular hexagon.

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)
