Question

22. Find y in Fig. 10 Find the values of the other angles as well. Fig. 10​

Answer 1

Answer:

y= 20°

6y=120°

2y=40°

Step-by-step explanation:

Suppose,Angle a be 6y

Angle b be y

Angle c be 2y

we know that a straight line =180°

so according to the question,

6y+y+2y=180°

9y=180°

y=180°/9

y=20°

so

Angle a= 6y= 6×20°= 120°

Angle b= y=20°

Angle c= 2y= 2×20°=40°
