Hey this question is from class 7 chapter 6 triangle and its properties this is a extra question pls help i will mark brainlist and be with them pls i will give 15 points

Answer 1

Step-by-step explanation:

Hlo mate...

Given angles of triangel ABC

3x , 2x , 4x

We know that

Sum of interior angle of triangle = 180°

$3x + 2x + 4x = 180 \\ 9x = 180 \\ \\ x = \frac{180}{9} \\ \\ x = 20$

Now angles if the triangles

$3x = 3 \times 20 = 60° \\ \\ 2x = 2 \times 20 = 40° \\ \\ 4x = 4 \times 20 = 80°$

Observe line Or Ray BAD. form linear pair

so sum of angles of linear pair = 180°

$\angle \:CAB \: + \angle \: CAD = 180 \\ \\ 40 + \angle \: CAD = 180 \\ \\ \angle \: CAD = 180 - 40 \\ \\ \angle \: CAD = 140$

So angle is 140°

You can also use exterior angle property......
