Sum of the ages of A and B is 55 years. If the ratio of their ages is 6:5. find their ages...

lys-0071 [83]

Answer:

A's age = 6x = 6 × 5 = 30 years.

B's age = 5x = 5 × 5 = 25 years

Step-by-step explanation:

here's the solution : -

let their ages be 6x and 5x

and we know sum of their ages = 55

So, 6x + 5x = 55

=》11x = 55

=》x = 55 ÷ 11

=》x = 5

A's age = 6x = 6 × 5 = 30 years.

B's age = 5x = 5 × 5 = 25 years

I don't need you to work it out, just theorem(s) i need to reach the answer :)

VikaD [51]

Not sure why such an old question is showing up on my feed...

Anyway, let $x=\tan^{-1}\dfrac43$ and $y=\sin^{-1}\dfrac35$ . Then we want to find the exact value of $\cos(x-y)$ .

Use the angle difference identity:

$\cos(x-y)=\cos x\cos y+\sin x\sin y$

and right away we find $\sin y=\dfrac35$ . By the Pythagorean theorem, we also find $\cos y=\dfrac45$ . (Actually, this could potentially be negative, but let's assume all angles are in the first quadrant for convenience.)

Meanwhile, if $\tan x=\dfrac43$ , then (by Pythagorean theorem) $\sec x=\dfrac53$ , so $\cos x=\dfrac35$ . And from this, $\sin x=\dfrac45$ .

So,

$\cos\left(\tan^{-1}\dfrac43-\sin^{-1}\dfrac35\right)=\dfrac35\cdot\dfrac45+\dfrac45\cdot\dfrac35=\dfrac{24}{25}$
