What is the value of y?

hai

a triangle's sum of interior angels is equal to 180°.

so we have this equailty

y+10°+50+2y = 180

3y+60° = 180.

to solve better, im throwing 60 near 180. 60° is going to be -60 cause of it.

3y=180-60 = 3y=120

now im dividing both 3. because both can divide by 3.

3y/3 = 120/3 = y=40

good luck(:
