In the triangle ABC, the height AN = 24 in, BN = 18 in, AC = 40 in. Find AB and BC.

Basile [38]

Step-by-step Answer:

AN is height, so A is perpendicular to BC. (See image attached).

BN = 18

AN = 24

AC = 40

All as labeled.

ABN is a right triangle, with AB = sqrt(18^2+24^2)=sqrt(324+576)=30

ACN is a right triangle, with CN = sqrt(40^2-24^2)=sqrt(1600-576) = 32

BC = BN + NC = 18 + 32 = 50

in sound and harmonics, the frequency of a vibrating string varies inversely to its length. A guitar string 20 inches long vibra

zmey [24]

20 inches is 400
10 inches is 200
5 iches is 100

So 20+10+5=35
Which means 400+200+100= 700

So the frequency of a 35 inch string is 700 cycles per second
