Question

In the given figure, the value of y is ______.

Options

• 30°

• 15°

• 20°

• 22.5°

Answer 1

In the given figure, the value of y is 20°.

Explanation:

Sum of all angles about a straight line given in the figure are equal to 180^o.

Then, 6y + y + 2y = 180°

⇒ 9y = 180°

⇒ y = `180^circ/9`

∴ y = 20°

So, the value of y is 20°.
