Angle RZT=110<br> Angle RZS=3s<br> Angle TZS=8s<br> What are angles RZS and TZS?
nekit [7.7K]
Angles RZT, RZS, and TZS form triangle RZT, so they sum to 180.  Thus, we have:

110+3s+8s=180

Simplifying, we have:

11s=70

Dividing by 11, we see that:

s=70/11

Therefore, RZS=3s=210/11, and TZS=8s=560/11.

Part1; The nth term of a geometric sequence is given by a_n = 4(0.75)^n-1, write the first five terms, and find the 5th partial
Lemur [1.5K]
Just take n=1,2,3,4,5 respectively to find out the first 5 terms.

First 5 terms = 4,3,2.25,1.69 respectively.

For the 5th partial sum, just add the first 5 terms.

5th partial sum = 10.34

....

First 4 terms : 5,8,11,14 respectively.

Now you need to find the other next 4 terms to find out the 8th partial sum.

17,20,23,26

8th partial sum = 124

Hope this helps:)
