11. Which line is parallel to y=5x+2/3 *
y = 5x + 3
y = -5x + 2/3
y =1/5 x + 7
y = -1/5 x + 9

y= 5x + 3

Step-by-step explanation:

Parallel lines have the same slope

Step-by-step explanation:

Given that,

The length of a ladder, H = 20 feet

The height of the wall, h = 15 ft

We know that,

h is perpendicular and H is hypotenuse

So,

Now using Pythagoras theoerm,

Hence, the angle made by the ladder and the ground is 48.59° and the ladder is 13.2 feet from the wall on the ground.
