perpendicular (p) = a

hypotenuse (h) = 3√2

sin 45 ° = p/h

a = 3√2 / √2

Therefore a = 3.

A girl studied for 5 2/3 hours daily. She devotes 2 4/2 hours of her time for science and mathematics. How much time does she de

enot [183]

Given :

Number of hours studied daily , $T=5\dfrac{2}{3}$ .

Time given for science and mathematics is , $t=2\dfrac{4}{2}$ .

To Find :

How much time does she devote for other subjects .

Solution :

Let , time devote for other student is x .

So , Time left for other subject = Total time - Time taken by science and mathematics .

$x=T-t\\\\x=5\dfrac{2}{3}-2\dfrac{4}{2}\\\\x=\dfrac{(5\times 3)+2}{3}- \dfrac{(2\times 2 )+4}{2}\\\\x=\dfrac{17}{3}-4\\\\x=\dfrac{17-(4\times 3)}{3}\\\\x=\dfrac{5}{3}=1\dfrac{2}{3}$
