A) center is (0,0)

Radius = r^2 = 225 => r = 15

b)center is (0,0)

Radius r^2= 178

=> r =13.34

C) center is (0,0)

Radius is r^2 = 49 => r = 7

If m ∥ n, m∠1 = (5x + 12)°, and m∠2 = (7x – 16)°, what is m∠3?

asambeis [7]

Answer:

98°

Step-by-step explanation:

m∠1 = m∠2

5x + 12 = 7x - 16; substitute the given

2x = 28

x = 14

m∠2 + m∠3 = 180; supplementary angles

82 + m∠3 = 180

m∠3 = 180 - 82

m∠3 = 98 degrees
