2x-9y and 11x + 3y - 12y - 9x
Answer:
3
Step-by-step explanation:
In a 30-60-90 triangle, the ratio of the shorter side to the longer side length is
. Therefore:

Just have to simplify
Answer:
M = (-3,1)
Step-by-step explanation:
We need to find the midpoint M of the line segment joining the points
A = (-5,7) and B = (-1, -5)
The mid point of the line segment joining the points (x₁,y₁) and (x₂,y₂) is given by :

Hence, the required point is (-3,1).
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.
