If the length of side a is 6 centimeters, the length of side b is 4 centimeters, and the length of side C is 7 centimeters, what is the measure of ZB? Round your answer

Hi myself Shrushtee

Step-by-step explanation:

This a triangle I take it.

Side a = 6cm

Side b = 4cm

Side c = 7cm

Find angle B

Using Cosine Rule

Cos B = (a^2 + c^2 - b^2)/ 2ac

Cos B = (6^2 + 7^2 - 4^2)/ 2 x 6 x 7

Cos B = (36 + 49 - 16)/ 84

Cos B = 69/84

Cos B = 0.8214

Angle B = 34.77 degrees (2 decimal places)

Hope this helps :-).

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.
