In this problem, we're given this set of rays and angles here, and we're told that, let's see, this is o, here in the center.
00:17
We're told, first of all, that this ray, ot, this ray right here, bisects this angle s -o -u, which means that this angle and this angle are each.
00:38
Equal okay and we're given that you angle u o v you o v this angle right here is 35 measure that angle is 35 degrees and the measure of angle yow w y o w so that's all the way across here is 120 then we're asked to find the other angles all right so first of all first of all by complementary angles or vertical angles excuse me by vertical angles since uv is 35 then that means that z o y this angle right here is also 35 okay a vertical angles okay so then by supplementary angles, we know that this angle right here, soz, so let's just write this up here, the measure of angle z -o -y is 35.
02:25
Okay? then we know that the measure of angle s -s -o -z is 180, minus the measure of angle z o y minus i should do it like this shouldn't i say that plus the measure of angle y o w so that's 180 minus the sum of 35 plus 120 which is 180 minus 1 .50 minus 155 which is 180 minus 155 which is just 25 degrees...
