Explain, in detail , the steps to find the measure of angle3

angle 3 =99

Step-by-step explanation:

so angle 1 and 2 are vertical angles which means they are the same measurement

angle 2=180-(90+31)

angle 2= 59

angle 1 =59

59+22=81

180-81=99

Option A 25 ft is the correct answer.

Step-by-step explanation:

Given that:

One square corral at a stable has an area 625 .

And one side corral is along a barn.

To find:

How much of a barn's wall is used for the edge of corral?

Solution:

First of all, kindly refer to the attached figure to have a better understanding of the given dimensions and situation.

Given that Corral is square shape with Area, A = 625

Formula for area of a square is given as:

Putting the value of A as given to find the Edge:

It is given that one side of Corral is along a barn.

So, barn's wall used for the edge of corral = 25 ft

Option A 25 ft is the correct answer.
