Question

PLEASE HELP ME OUT THANK YOU

Solve for y.



y = 60

y = 16

y = 10

y = 34

Answer 1

`\sf y = 10`

Explanation:

Since equilateral triangle's angles and sides are equal.

And each angle is 60°.

So,

`\sf \angle A = 60^\circ`

Substitute the given value:

`\sf (5y + 10)^\circ = 60^\circ`

Subtract 10° on both sides.

`\sf (5y + 10- 10 )^\circ = (60-10)^\circ`

`\sf 5y = 50`

Divide both sides by 5.

`\sf (5y)/(5) = (50)/(5)`

`\sf y = 10`

Therefore, the value of y is 10.
