Which equation represents a circle with a center at (-4,9) and a diameter of 10 units? O (X-9)2 + (y + 4)2 = 25
O (x + 4)2 + (-9)2 = 25
O (X - 9)2 + (y + 4)2 = 100
O (x + 4)2 + (- 9)2 = 100

a - base

b - exponent

so,

a. 32 degrees

step-by-step explanation:

here we have to use the rule.

m∠e = 1/2 (major arc - minor arc)

m∠e = 1/2 (212 - 148)

m∠e = 1/2 (64)

m∠e = 32 degrees

answer: a. 32 degrees

you

answer: 100
