divide 15 by three
Answer:
25/7 acres or 3 4/7 acres
Step-by-step explanation:
The sold 2/7 of the land.
1 - 2/7 = 7/7 - 2/7 = 5/7
They have 5/7 of the land left.
5/7 of 5 acres = 5/7 × 5 acres = 25/7 acres = 3 4/7 acres
The <em>correct answer</em> is:
d) Construct the angle bisector of each angle in the triangle
Explanation:
The incenter, or center of an inscribed circle, is the point where the angle bisectors of a triangle intersect. This means the first thing we will need to construct is the bisector of each angle of the triangle.
For this case we have the following system of equations:

Equating both equations we have:

We must find the solutions, for this we factor. We look for two numbers that, when multiplied, result in 4 and when added, result in 5. These numbers are 4 and 1:

Then, the factorized equation is of the form:

Thus, the solutions are:

We look for solutions for the variable "y":

Thus, the system solutions are given by:
