Look at this triangle work out length BC

Andreas93 [3]

Answer:

The length of BC is √105 cm or 10.2 cm.

Step-by-step explanation:

You have to apply Pythagoras Theorem, c² = a² + b² where c represents hypotenuse, a and b are the sides :

${c}^{2} = { a}^{2} + {b}^{2}$

$let \:a =BC \:, \: b = 8 \: , \: c = 13$

${13}^{2} = {BC}^{2} + {8}^{2}$

$169 = {BC}^{2} + 64$

${BC}^{2} = 169 - 64$

${BC}^{2} = 105$

$BC = \sqrt{105}$

$BC = 10.2 \: cm \: (3s.f)$
