In rectangle ABCD, diagonal AC, which is 20 inches in length, makes an angle of 35o with the base AB. a. Find AB, the base of the rectangle, to the nearest tenth of an inch. Find CB, the altitude of the rectangle, to the nearest tenth of an inch.

sorry, i don't know i just need points, i'm new here. chao

i am sorry it just submitted an answer but the answer is 365 boys. hopes this

step-by-step explanation:

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)
