WHAT WOULD THIS BEEEEEEE!!
miv72 [106K]

Answer:

c) 30

Step-by-step explanation:

since the lines are parallel, 75° = 2x + 15°

this is because when two parallels lines are intersected by the same line, all respective angles are equal. Also, opposite angles on a line are equal too.

So now that u have 75 = 2x + 15, just solve for x by simplifying:

75 = 2x + 15

60 = 2x

30 = x

so the answer is c) 30

hope this helps!

Find a2 and a3 for the geometric sequence 4, a2, a3, 108.
LekaFEV [45]

9514 1404 393

Answer:

  a2 = 12

  a3 = 36

Step-by-step explanation:

Terms of a geometric sequence have a common ratio. If we call that ratio r, then we have ...

  a2 = 4r

  a3 = (a2)r = 4r^2

  108 = (a3)r = 4r^3

  27 = r^3 . . . . . . . . . . . divide by 4

  3 = r . . . . . . . . . . cube root

__

  a2 = 4(3) = 12

  a3 = 12(3) = 36
