Question

please fast..... please help me​

Answer 1

Answer:

sum of angle in a line= 180°

y+2y+6y = 180°

9y =180°

y = 180÷9=20

ANGLES:

(i) y=20°

(ii) 2y=2×20=40°

(iii) 6y= 6× 20 =120°

Answer 2

Required Solution :

As we know a straight angle = 180°

and, it's divided into 3 angles .

↓↓

First, find the value of x .

→ 6y + y + 2y = 180°

→ 9y = 180°

→ y = 180 / 9 = 20°

Hence,

6y = 20 × 6 = 120°

y = 20°

2y = 20 × 2 = 40°
