Question

SEUDULLU
B. In a right triangle ABC right angled at B, in which AB = 14 cm and AC = 50 cm. Find BC.​

Answer 1

Answer:

BC = 48cm

Step-by-step explanation:

In the picture it is given that AC = 50cm and

AB = 14cm

we can find BC by applying

Pythagoras theorem which says

${(hypotenuse)}^{2} = {(sum \: of \: the \: two \: sides)}^{2}$

Here, hypotenuse = AC =50cm

The two sides are = AB = 14cm and BC =?

${AC}^{2} = {BC}^{2} + {AB}^{2}$

by Pythagoras theorem we have ,

${(50)}^{2} = {BC}^{2} + {(14)}^{2}$

$= > 2500 = {BC}^{2} + 196$

$= > 2500 - 196 = {BC}^{2}$

$= > 2304 = {BC}^{2}$

$= > BC = \sqrt{2304}$

$= > BC = 48cm$
