Question

If triangle ABC is an isosceles triangle with angle c is equals to 90 degree and ac is equals to 5 cm then ab is equals to?

Answer 1

Answer:

AB =

$5 \sqrt{2cm}$

Step-by-step explanation:

Here,

triangle ABC is an isosceles triangle

angle C=90

AC=5cm

so, AC=BC=5cm

then,

by phythagorous theorem

$(ac )^{2} + (bc) ^{2} =( ab) ^{2} \\ \\ 5 ^{2} + {5}^{2} = (ab )^{2}$

$ab = \sqrt{25 + 25}$

$ab = \sqrt{50}$

$ab = 5 \sqrt{2 \: cm}$
