Question

help me find the answer for this question​

Answer 1

Explanation:

For this question, we need to understand the concept of reflex angles.

Reflex angles :-

• The angles which are beyond the given input are reflex angles
• They sum up to give 360° as a total.

In this question, we're gonna do the same thing that it sum it up to 360° to find y.

》$\tt{158 + y + 20 + y + 60 = 360}$

》$\tt{238 + 2y = 360}$

》$\tt{2y = 360 - 238}$

》$\tt{2y = 122}$

》$\tt{y = \dfrac{122}{2}}$

$\tt{ = 61 \ degree}$

So, we've found the value of y as 61°.

• y + 20 = 61 + 20 = 81°
• y + 60 = 61 + 60 = 121°

Whenever you get such diagram, make sure if it makes a circle, this ought to sum up as 360°.

In triangle it is 180°. And again in quadrilaterals, it's 360°.
