indeed
Step-by-step explanation:
Answer:
its 90 bro whenever you see that square on a corner its always 90 degrees
Step-by-step explanation:
First, expand to make it easier
y=x(x^2+5)(x^2+5)
y=x(x^4+10x^2+25)
y=x^5+10x^3+25x
differentiation
y'=5x^4+30x^2+25 is the derivitive
Angle A would be 10 degrees.
Complementary angles add to 90 degrees.
So 90-80=10
