Find the values of x, y, and z.

• x = 82˚, y = 82˚, z = 93˚

• x = 98˚, y = 82˚, z = 93˚

• x = 82˚, y = 98˚, z = 87˚

• x = 82˚, y = 98˚, z = 93˚

Find the equation of a circle with a center at (1, -2) and a point on the circle at (5, 4).

• (x-1)² + (y+2)² = 52

• (x+1)² + (y-2)² = 52

• (x-5)² + (y-4)² = 52

• (x+5)² + (y+4)² = 52
