How do you find a missing side of a triangle using SOH CAH TOA

katrin2010 [14]

Answer:

See explanation and attachment

Step-by-step explanation:

SOH CAH TOA is a mnemonic.

SOH means $\sin \theta=\frac{Opposite}{Hypotenuse}$

CAH means $\cos \theta =\frac{Opposite}{Hypotenuse}$

TOA means $\tan \theta=\frac{Opposite}{Adjacent}$

Given an angle and a side of a right angle triangle, you can use the appropriate ratio to find the missing side.

For instance, find x in the diagram in the attachment.

In this case the best ratio to use is TOA.

$\tan 60\degree=\frac{\sqrt{3} }{x}$

$\implies x=\frac{\sqrt{3} }{\tan 60}$

$x=\frac{\sqrt{3} }{\sqrt{3} } =1$

All the other ratio also follow the same pattern

NB: Your calculator in degree should give $\tan 60\degree=\sqrt{3}$

A=number Adult tickets;S=A+74= number Student tickets

Total tickets=adult tickets + student tickets

724=A+(A+74)

724=2A+74 Subtract 74 from each side

650=2A divide each side by 2

What is 0.003is 1/10 of

Whitepunk [10]

0.003 is 1/10 of 0.03.

Just multiply the 0.003 by 10 and you'll get the result. The easiest way to multiply such numbers is to move the dot one position to the right (it would be 2 positions if multiplying by 100, 3 by 1000 etc.). You can do the same with dividing, just remember to move to the left then.
