Question

Q. Let us assume a triangle ABC which has only one acute angle (say ZA) Then we have

the following three cases:

(1) The other two angle (ZB and ZC) are right angles

Then ZA+ ZB+ ZC = LA + 90°+90° = ZA+ 180'>180" which is not possible,

(II) Then other two angles (ZB and 2C) are obtuse angles Then ZA+ ZB +ZC> 180° which is not possible

(iii) One angle (say ZB) is right and the other angle( 2C) is obtuse.​

India is one of the mega biodiversity centres in the world and has two of the world's 18 'biodiversity hotspots' located in the Western Ghats and in the Eastern Himalayas (Myers 1999). The forest cover in these areas is very dense and diverse and of pristine beauty, and incredible biodiversity.
