Here in this problem given, rt12, ts 9, rs equals 15, and angle trs is 30 degrees.
00:10
This is the triangle.
00:12
Let's draw there.
00:20
Rts.
00:23
And here, w, x, and y.
00:33
Now here given, rs is 12 and ts is 9.
00:39
R .s 12, ts9 units, and, sorry, rt12, this one, and ts9, and rs -9, this one, and t -s -9, and r -s -15.
00:57
So this one will be 5, 15, and angle, t -r -s is 30 -degree.
01:06
This is 30 -degree.
01:07
And another triangle given y w x angle y w x angle y w x is 30 degree this angle is 30 degree um w y 16 units y x 12 units and w x 25 units now we have to answer thus triangle r st is congruent with the triangle wxy.
01:37
Now, here we have to check the congruency criteria...
