Question

AABC is a right triangle. If AC = 4 and BC = 10, find AB. Leave your answer in simplest radical form.

Answer 1

`2 √(21) is \: the \: ans`

Explanation:

given;abc is a right angled triangle.

by takingr eference reference angle c

p=ab=? ,h=bc=10 ,b=ac=4.

by the Pythagoras relation we get;

`p = \sqrt{h {}^(2) - b {}^(2) }`

so ,p=

`\sqrt{10 {}^(2) - 4 {?}^(2) }`

==

=

`= 2 √(21)`

is ans
