OMG HELP PLEASE PLES

3.09m

Step-by-step explanation:

refer to attached

by Pythagorean theorem,

x² = 2.8² + 1.3²

x² = 7.84 + 1.69

x² = 9.53

x = ±√9.53

x = ±3.09

since diagonal cannot be negative, hence we pick the positive number

x = 3.09m

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)
