A right-angled isosceles triangle has an area of 50 square units. Its hypotenuse is (in units):
The pie chart given below shows the expenditure (in percentage) of Aditya. The monthly income of Aditya is₹54,000. 
How much does he spend (in Rs) on food?
The angles of triangle are such that one is average of other two, then the angles are:
1. \(\dfrac{\pi}{6},\ \dfrac{\pi}{3},\ \dfrac{\pi}{2}\)
2. \(\dfrac{\pi}{3},\ \dfrac{\pi}{3},\ \dfrac{\pi}{2}\)
3. \(\dfrac{\pi}{6},\ \dfrac{\pi}{3},\ \dfrac{\pi}{4}\)
4. \(\dfrac{\pi}{2},\ \dfrac{\pi}{2},\ \dfrac{\pi}{3}\)
