Question

in the figure angle B=90 ,AB=5cm,AC=13cm find the value of C
​

Answer 1

Step-by-step explanation:

In ΔABC right angled at B,

By Pythagoras Theorem,

(AC)² = (AB)² + (BC)²

⇒ 13² = 5² + (BC)²

⇒ 169 = 25 + BC²

= > BC = \sqrt{169 - 25}

=>BC= √169−25

= > BC = \sqrt{144}

=>BC= √144

= > BC = {\sqrt{(12)^2}

or,

BC = 12 unitsBC=12units
