Question

pls help me to find the answer ​

Answer 1

Answer:

1x+2x+3x=360°

1x+2x=180°

180°+3x=360°

3x=360°-180°

3x=180°

x=180°/3

x=60°

1x=1×60°=60°

2x=2×60°=120°

3x=3×60°=180°

1x+2x+3x=360°

60°+120°+180°=360°

Answer 2

Step-by-step explanation:

Let the first angle = x

Therefore, the second and third angles are 2x and 3x.

1x + 2x + 3x = 360 degree (sum of the angles of the quadrilateral).

6x = 360 degree

x = 360/60

x = 60 degree

2x = 2 × 60 = 120 degree

3x = 3 × 60 = 180 degree

Hence, the smallest angle is 60 degree and the largest angle is 180 degree.
