Question

in a right angle triangle ABC, angle B=90° AC=17cm and AB=8cm find the length of BC​

Answer 1

Answer:

∆ABC,B=90° , AC=17, BC=8. To find:AB=? =>AB=√225=15cm.

Answer 2

Step-by-step explanation:

$There \: is \: ∆ABC, B=90°, AC=17cm \: and \: AB=8cm.$

$as \: it \: is \: a \: Equiangular Triangle \:$

$we \: got \: from \: pithagora's \: theorem$

$ab^{2} + bc ^{2} = ac^{2}$

$or, \: bc = \sqrt{ac^{2} - ab^{2} }$

$or,bc = \sqrt{289 - 64}$

$or,bc = \sqrt{225}$

$or,bc = 15$

$The \: answer \: is \: 15cm.$
