Determine the area of a triangle with sides of the following length:
a = 19 m
b = 20 m
c = 21 m
a. 192 m2
c. 172 m2
b. 180 m2
d. 183 m 2

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
