So in this question, basically, we need to find this angle that is c, d, b, and i'm just marking it as a, and we need to find this angle that is i am marking as b.
00:10
So basically here, we need to find first angle as c, d, b.
00:17
Second is, we need to find angle d, b, c, and third angle, we need to find angle a, b, c.
00:27
So we know that in triangle, in triangle a, d, b, 40 degree plus 107 degree plus x degree is equal to 180 degree.
00:52
This is angle sum property of a triangle.
00:55
So that sum of all interior angles of a triangle is simply 180.
01:05
Some of all interior of triangle is simply 180.
01:11
So from here, x is simply 180 minus 40 minus 107 degree.
01:20
So if we simplify, we simply get x as simply 33 degrees...
