If the angles of a triangle are (2y - 5)degrees, (y + 20)degrees, and (3y-5) degrees what are the values of the angles

Step-by-step explanation:

Let's solve:

As we know that the sum of angles of traingle adds to 180°

Collect like terms

51 2/3 , 48 1/3 and 80 degrees.

Step-by-step explanation:

The 3 angles add up to 180 degrees.

2y - 5 + y + 20 + 3y - 5 = 180

6y + 10 = 180

6y = 180 - 10

6y = 170

y = 170 / 6 = 28 1/3 degrees.

So the 3 angles are  2(28 1/3) - 5,   28 1/3 + 20 and 3(28 1/3) - 5.
