Question

MZTRI 3x - 5, MZIRB = x + 27, and mTRB Does RI bisect TRB?

Answer 1

1) Let's draw that to better understand this

The Bisector Theorem states that the angle bisected is equally divided

since the angle TRB = 86º . Besides that the m TR

To determine whether it does bisect let's set an equation in which x +27 = the half of 86º

x+27 =43

x=16

3x -5 =43

3x =48

x=16

So, RI bisects the angle TRB, for each angle is half of the measure of TRB.
