plsss guyss answer this papers was going on plsss wrong answer will reported​

Answer 1

Answer:

1) 30

2) 60

3) 90

4) 120

Step-by-step explanation:

angle 1 can be assumed as $x$  . so then angle 2 would be $3x$ ( 3 ×$x$ ) . Angle 3 would be $2x$ . sum of a triangle is 180 degrees. hence, we can form an equation $x+2x+3x= 180$ . After solving it the answer is $x=30$ .

Angle 1 = $x$ = 30 degrees

Angle 2= $3x$ = 90 degrees

Angle 3 = $2x$ = 60 degrees

Angle 4 is an exterior angle. (formula: Exterior angle = sum of interior non adjacent opposite angles )

Angle 4:

method 1:

30 + 90 = 120

method 2:

180 - 60 = 120 ( angles on a straight line )
