Find the arc measure of AB.<br> The measure of arc AB = ______ degrees
mariarad [96]
The picture is difficult to read, but it looks like
  ∠ADB = 2x²
  ∠ACB = 10x
These two angles have equal measure, so you have
  2x² = 10x
  2x(x -5) = 0 . . . . . subtract 10x and factor
  x = 0, or x = 5

The measure of arc AB is twice the measure of either inscribed angle, so would be
  arc AB = 2×10x
  = 2×10×5
  = 100 . . . . . degrees

Arc AB is 100°.

Please someone help me I’m confused
insens350 [35]

Answer:

a2 =14

a4 = 22

a11 = 50

Step-by-step explanation:

an = 10 + (n-1) *4

n is the term number

Let n =2

a2 = 10 +(2-1)*4 =10 +(1)*4 = 14

Let n =4

a4= 10 + (4-1)*4 = 10 *3*4 = 10+12 = 22

Let n = 11

a11 = 10 +(11-1)*4 = 10 *10*4 = 10+40 = 50
