Answer:
He needs to makes sure both equal to 0.50 or less
Step-by-step explanation:
All three angles on a triangle always equal 180°.
Example: 100°+40°+40°=180°
102+39=141°
180-141=39°
x = 39°
I believe the answer is 80 cuz it's in the middle
x^2 y^2(x+y)(x^2 - xy + y^2)
x^2 y^2(x^3 + y^3)
(x+y)(x^2 - xy +y^2)
