Is it possible draw a right triangle with and obtuse angle? if so draw it in the box if not write impossible. is it possible guys & girls?

It is not possible. Since one of the angles has to be a right angle, the other two angles would have to add to 90. Therefore, neither of these angles can be more than 90 degrees. 

Hope this helps

A= r2 × 3.14 7x7 ↓ ↓ 49 × 3.14 = 153.86 → 153.9
