Question

a right angled triangle has 5cm opposite side, 9cm adjacent side. find length of hypotunise
​

Answer 1

• Perpendicular=P=5cm
• Base=B=9cm

Hypotenuse be H

Apply Pythagorean theorem

$\\ \sf\Rrightarrow H^2=P^2+B^2$

$\\ \sf\Rrightarrow H^2=5^2+9^2$

$\\ \sf\Rrightarrow H^2=25+81$

$\\ \sf\Rrightarrow H^2=106$

$\\ \sf\Rrightarrow H=\sqrt{106}cm$
