*urgent, will mark brainliest answer* i really need with this,

1.

The area of the circle is given by , so in your case it is squared feet.

The whole center is given by a center angle of 360°, but you're only interested in the 152° sector.

So, we have the following proportion:

which means

solving for x, we have

2.

Given the center and the radius , the equation of a circle is

Plug your values to get

Which you can rewrite as

Or, if you prefer,

step-by-step explanation:

ask goog great chance of finding the solution there

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)
