For problem 16, we're given a figure.
00:03
We're also given angle rsq, which is this angle here, is 58 degrees, so we'll label that here.
00:13
We're given segment rq, which is the segment here, is 49 units long, and segment tq, which is this segment here, is also 49 units long.
00:25
They want us to find the measure of angle rst, this big angle here.
00:32
So just looking at what we're given, we can see that our q is congruent to tq, which is great news because we know some theorems that we can use to help us find angle rst.
00:50
Because the converse of the angle bisector theorem says that if a point is in the interior of an angle, so in this case, q is on the inside of angle rst.
01:02
T.
01:04
This is the interior of the angle.
01:06
So q is on the inside.
01:07
So if the point is on the interior and it's equidistant from the sides of the angle.
01:13
So the side of the angle are rs and t...
