So looking at the picture in problem number 32, we can identify that this is an isosceles trapezoid because the two legs have these double tick marks on them.
00:14
So we have an acesalice trapezoid, which means we can apply all four of these statements as we solve.
00:21
In part a, we are looking for angle t.
00:26
Notice that angle t is the upper base angle, along with angle.
00:33
Q.
00:34
So angle q is equal to angle t because our upper base angles are equal.
00:45
Thus, angle t is equal to 47 .5 degrees.
00:54
Question b asks us about angle r.
00:57
Angle q and angle r are supplementary angles, because we have two pairs of supplementary angles in trapezoids.
01:13
Thus, q and r together, when you add them, will be 180 degrees...
