Question

Gif AABC is an isosceles triangle with angle C = 90° and AC = 5 cm, then AB is equal
to
(a) 2.5 cm
(b) 5√2 cm
(c) 3.5 cm
(d) 3.8 cm​

Answer 1

Answer:

AC = BC = 5 cm

∴ AB^2 = $\sqrt{AC^2 + BC^2}$

= $\sqrt{5^2 + 5^2}$ = $\sqrt{50}$ = $5\sqrt{2}$cm^2

Hence option [A] is the right answer.Step-by-step explanation:
