P-5??? It's an expression
A) A triangle can have two congruent angles.
It's called an Isosceles Triangle
No. To test whether a graph is a function or not you do the vertical line test where if a vertical line touches more than one point it is not a function
The inscribed circle has its center at the point of intersection of the angle bisectors, which also happen to be the medians. Hence the altitude of the triangle is 3 times the radius, or 12 inches.
The side length of this triangle is 2/√3 times the altitude, so the area is
... Area = (1/2)·b·h = (1/2)·(24/√3 in)·(12 in)
... Area = 48√3 in² ≈ 83.1384 in²
