Find the 52nd term of the following arithmetic sequence.<br> 17, 22, 27, 32, ...

rewona [7]

Answer:

17; 22; 27; 32

the terms increase by 5 each time

17 + 5 = 22 (the second term)

17 + 5 * 2 = 27 (third term)

So to get to the 52nd term, we have to add 5* 51 = 255 to 17

17 + 255 = 272

50 POINTS + BRAINLIEST TO CORRECT ANSWER!! TRIG/GEO

WINSTONCH [101]

Option C:

We can find the value of PR using law of cosines.

Solution:

Given data:

∠Q = 18°, r = 9.5, p = 6.0

To find which length could be find in the triangle:

Law of cosines:

$a^{2}=b^{2}+c^{2}-2 b c \cos A$

Substitute a = q, b = r, c = p and A = Q

$q^{2}=r^{2}+p^{2}-2 r p \cos Q$

If we substitute the values given, we can find q.

q = PR

$PR^{2}=r^{2}+p^{2}-2 r p \cos Q$

Hence we can find the value of PR using law of cosines.

Option C is the correct answer.
