Answer 2

Answer:

The value of y is 14.

Step-by-step 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, $2x^\circ+50^\circ+(5y+10)^\circ=180^\circ$

$50+50+5y+10=180$

$110+5y=180$

$5y=70$

$y=\frac{70}{5}$

$y=14$

Therefore, the value of y is 14.
