Question

What is the value of y?

Answer 1

Answer:

C, 40 degrees

Step-by-step explanation:

All the angles of a triangle add to 180 degrees according to the Triangle Sum Theorem.

Since all angles sum to 180, we can set all the values to add to 180.

We have:

$2y+y+10+50=180$

Combining like terms, we have:

$3y+60=180$

Subtracting 60 from both sides gets us

$3y=120$

Dividing by 3 from both sides equals

$y=40$

Answer 2

Answer:

I think the value of y is 40

Step-by-step explanation:

Here,

2y+ y+ 10+50=180°( sum of all angles of triangle)

or, 3y+ 60=180

or, 3y=180-60

or, 3y=120

or, y= 120÷3

:.y= 40
