Welcome to numerid.

Another problem here.
00:03
So for this given trust, we have to find the angle a, b, e, which is this.
00:09
Okay.
00:11
So without it's beginning.
00:13
So we can go like this as well.
00:18
It's a backtracking.
00:19
So i start by angle a, b, d, writing angle a, b, d, b, d, plus angle d, b, e.
00:28
Okay.
00:29
So angle d, b, e.
00:29
Okay.
00:29
So angle d, b, b, now angle abd is already given to be 90 degrees so we don't worry but what about angle dbe how do we find it correct so we have to think about it now see to find a dbe if you see you can already see that this a f and b e are parallel to each other and this is just a line going through it's a transversal or even you can think of a b, ac, ac transversal, right? so that means what? if i just, i have a idea.
01:12
So what i will do? i will draw another image.
01:20
And when if, oh, oh, no, that's not, that's not what i want.
01:30
So i know.
01:34
Now you notice, it will be much, much 10 times easier for you.
01:40
See, they have told a is parallel b .e...
