Inessa [10]2 years ago
5 0

Answer:

The center is (0,0) and the radius is 2

Step-by-step explanation:

The equation of a circle is

(x-h)^2 + (y-k)^2 = r^2  where (h,k) is the center and r is the radius

x^2+y^2=4

(x-0)^2 + (y-0)^2 = 2^2

The center is (0,0) and the radius is 2

Write and solve an equation to find the complement of a 42 degree angle. tell what the variable represents.
EastWind [94]
The complememtn is the angle that adds to the angle to get 90

so

the complement of angle a is b if
a+b=90

so

the comlmement of a 42 degree angle is
42+complement=90
complmement=c
42+c=90
minus 42 both sides
c=48

the measure of the complement is 48 degrees
c is the complement
