180 degrees. in an equilateral triangle, each angle is 60 degrees
Answer:
use Pythagoras theorem
the missing side is base
Step-by-step explanation:
pythagoras theorem
h^2 = p^2 + b^2
73^2 = 48^2 + b^2
5329 = 2304 + b^2
5329 - 2304 = b^2
3025 = b^2
√3025 = b
55 = b
It is centered at (h,k) --> (0,0) and has a radius 9
The equation of the circle is
