Question

solve this following​

Answer 1

This is simple

as we know straight angle = 180

then 6y + y + 2y = 180

now 9y = 180

so y = 180/9

therefore y = 20

correct answer = (c) 20

hopes it helps be brainly

Answer 2

Here is your answer ❤️⏬

In diagram

We know that,

The sum of angles in straight Line is 180°

Hence, We can say that

6y + y + 2y = 180°

9y = 180°

y = $\sf \frac{180°}{9}$

y = $\sf \frac{\cancel{180°}^{\: \: \cancel9 × 20}}{\cancel{9}}$

y = 20°

Option (c) is right ✔️

I hope it helps you ❤️✔️
