Answer:

\sf \sin A=\boxed{\dfrac{5}{13}}\quad\cos A=\boxed{\dfrac{12}{13}}\quad\tan A=\boxed{\dfrac{5}{12}}

Step-by-step explanation:

<u>Trigonometric ratios</u>

\sf \sin(\theta)=\dfrac{O}{H}\quad\cos(\theta)=\dfrac{A}{H}\quad\tan(\theta)=\dfrac{O}{A}

where:

  • \theta is the angle
  • O is the side opposite the angle
  • A is the side adjacent the angle
  • H is the hypotenuse

Given:

  • \theta = A
  • O = BC = 5
  • A = AC = 12
  • H = AB = 13

\implies \sf \sin A=\dfrac{5}{13}\quad\cos A=\dfrac{12}{13}\quad\tan A=\dfrac{5}{12}

Mr. Smith invests a certain amount of money at 8% and twice as much at 5%. If his annual income from the two investments is $720
professor190 [17]

The amount invested by Mr.Smith in 5% is $240 .

<u>Step-by-step explanation:</u>

We have , Mr. Smith invests a certain amount of money at 8% and twice as much at 5%. If his annual income from the two investments is $720 . Let us suppose that Mr.Smith invest $x so :

Amount of money invested in 5% is \frac{5x}{100} . And, amount of money invested in 8% is twice that of 5% i.e. \frac{(2)5x}{100} = \frac{10x}{100} .

Now, total investment is $720 so,

\frac{5x}{100} +( \frac{(2)5x}{100} = \frac{10x}{100} ) = $720

⇒ \frac{5x}{100}  + \frac{10x}{100}  = 720

⇒ \frac{15x}{100}    = 720

⇒ \frac{100(720)}{15}    = x

⇒ x = 4800

The amount invested by Mr.Smith in 5% is \frac{5x}{100} i.e.\frac{5(4800)}{100} = 240. ∴ The amount invested by Mr.Smith in 5% is $240 .
