Question

Height and base of a right angled triangle are 24 cm and 18 cm find the length of its hypotenus.Select the correct alternative.
(A) 24 cm
(B) 30 cm
(C) 15 cm
(D) 18 cm

Answer 1

Let height be p and base be b and hypotenuse be h.
p=24,b=18
$h = \sqrt{ {p}^{2} + {b}^{2} } \\ = > h = \sqrt{ {24}^{2} + {18}^{2} } \\ = \sqrt{576 + 324} \\ \sqrt{900} = 30$
Therefore the answer is option (a) 30°.
