Find the length of NC, measure of angle C and the measure of angle T

NC = 7.7

C = 63.6°

T = 26.4°

Step-by-step explanation:

✔️Apply pythagorean theorem to find the length of NC:

NC = √(17.2² - 15.4²) = √58.68

NC ≈ 7.7

✔️Apply trigonometric function to find Angle T:

Reference angle = T

Hypotenuse = 17.2

Adjacent length = 15.4

Apply CAH, thus:

T ≈ 26.4°

✔️C = 180 - (90 + 26.4) (sum of triangle)

C = 63.6°

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

answer: just subtact the units and then add the non negative : happy to
