NEED HEP WILL GIVE BRAINLIEST IF YOU SOLVE ALL 3

1) cant solve, you accidentally cropped out the bottom

2) ∠ABC=60°

3) x=25°

Step-by-step explanation:

1) cant solve, you accidentally cropped out the bottom. Let me know what the figure opposite the angle (5x-70) is and I can figure out the answer.

2)∠ABC=(45+15) (VERTICALLY OPPOSITE)

∠ABC=60°

(x=12.5°)

3) (x) + (3x-10) =90

4x -10 = 90

4x=100

x=25°

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)
