Answer» Hypotenuse = p cm Other SIDE = q cm Given, q + 1 = p We know, hypotenuse² = height² + base² => ( p )² = ( q )² + ( base )² => ( q + 1 )² = q² + base² => q² + 1 + 2q = q² + base² => 1 + 2q = base² => 1 + q + q = base² => p + q = base² or REMAINING side² => √ ( p + q ) = remaining side $\rightarrow \sqrt{p + q} \: \: cm \: \: \: = remaining \: side$
