use pythagoras theorem...

$$hypotenuse ^{2} = base ^{2} + perpendicular ^{2}$$

anonymous · Answer

here you have hypotenuse = 20 and base = 14

nnesha · Answer

same like last one same formula
 do it first and let me know what you get

anonymous · Answer

and you have to find the value of perpendicular...
so put the given value u will get the answer

nnesha · Answer

|dw:1427581455758:dw|
$$\huge\rm a^2 +b^2 =c^2$$ 
again longest side which is hypotenuse is c
