Answer 2

The value of y is 14.

Explanation:

To find : What is the value for y?

Solution :

As shown in the figure given,

The triangle given is an isosceles triangle as two sides are equal.

By property of isosceles triangle the two opposite angles are equal.

So,
`2x^\circ=50^\circ`

By property of triangle sum of angle of triangle is 180°.

So,
`2x^\circ+50^\circ+(5y+10)^\circ=180^\circ`

`50+50+5y+10=180`

`110+5y=180`

`5y=70`

`y=(70)/(5)`

`y=14`

Therefore, the value of y is 14.
