Answer:

a(5)=8

Step-by-step explanation:

it is geometric so we will use this equation:

a(n)=a1*(r)^(n-1)

and we have a(1)=128 , r=1/2

So a(n)=128*(1/2)^(n-1)

fifth term : a(5)=128*(1/2)^(5-1)=8

hope this helps

Use the diagram shown to find x.

marusya05 [52]

X would equal 70°.

For every triangle, all interior angles add up to 180°. This means that we can add together 42 and 68 to get 110°. Because the sum of all interior angles in a triangle must be 180°, we subtract 110 from 180 to see how much more we need, which gets us 70°.

I hope this helps!
