find the measure of the arc or angle indicated. assume that lines which appear tangent are tangent
Serjik [45]

Answer:

Option (1)

Step-by-step explanation:

By the property of alternate segment theorem,

"Angle formed between the tangent and the chord in a circle measures the half of the measure of the intercepted arc"

m(∠EFG) = \frac{1}{2} × m(minor arc FG)

minor arc FG = 2m(∠EFG)

                      = 2(76°)

                      = 152°

Therefore, Option (1) will be the correct option.

Somebody help me with this please!!
Slav-nsk [51]

Notice the following pattern:

2 - 0 = 2

6 - 2  = 4

12 - 6 = 6

20 - 12 = 8

It's reasonable to assume that consecutive terms in the sequence differ by increasing multiples of 2, so that for the next number (call it x) we expect to see

x - 20 = 10  ==>  x = 30

and for the number after that (call it y) we would see

y - x = y - 30 = 12  ==>  y = 42
