The equation for finding the circumference of a circle:
If the radius of this circle is 1, then that means the diameter is 2. We multiply 2 by π to get our answer: 2π or approximately 6.283.
Answer:
A = 60.07°
Step-by-step explanation:
Sin A = 
Sin A = 
Sin A = 0.867
A = Sin⁻¹ 0.867
A = 60.07°
I think it’s 6
Sorry if I’m wrong
((x+2)(x+2))-((x-5)(1))=A
x^2+4x+4-x+5=A
x^2+3x+9=A
