You need to do 2y+y+10+50=180. Then you'd combine like terms to make 3y+60=180 then to get rid of the sixty subtract it from 180 to make 3y=120 then divide by three to get y by itself so 120 divided by three is 40 which makes y whisk forty. Hope this helped.

Answer:

The value of y = 40

Step-by-step explanation:

Measure of one angle of the triangle is given to be 2y

Measure of second angle of the triangle is given to be y + 10

Measure of the third angle of the triangle is given to be 50

Now, By using the angles sum property of a triangle, We have :

Sum of all the three angles of a triangle is always supplementary

⇒ ∠1 + ∠2 + ∠3 = 180°

⇒ 2y° + (y + 10)° + 50 = 180°

⇒ 3y + 10 + 50 = 180°

⇒ 3y = 120

⇒ y = 40

Hence, The value of y = 40
