Question

Solve for y.



Enter your answer in the box.

Answer 1

5y + 10 = 60
5y = 50
 y = 10

Answer 2

Answer: The value of y is 10.

Explanation:

From the given figure it is noticed that in triangle ABC all the sides are equal it means it is an equilateral triangle.

According to the properties of equilateral triangle all the interior angle of an equilateral trial are 60 degree.

From the given figure the angle A is equal to 5y+10 degree and it is an interior angle of an equilateral triangle. So,

$5y+10=60$

$5y=50$

$y=10$

Similarly angle C is equal to 6x+6 degree and it is an interior angle of an equilateral triangle. So,

$6x+6=60$

$6x=54$

$x=9$

The value of x is 9, but we need to find only the value of y which is equal to 10.
