Question

Solve the following questions.
In AABC,
angle B AB=11 and BC=60cm. Find AC​

Answer 1

Answer:

$\huge \underline{ \mathfrak{ \red{given}}} : -$

• AB=11 cm
• BC=60 cm

$\huge \underline{ \mathfrak{ \red{to \: find}}} : -$

• Length of AC

$\huge \underline{ \mathfrak{ \red{solution}}} : -$

we have,

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

$\implies \: {AC}^{2} = {11}^{2} + {60}^{2} \\ \implies \: {AC}^{2} = 121 + 3600$

$\implies \: {AC}^{2} = 3721$

$\implies \: {AC}^{2} = {61}^{2}$

$\implies \: AC = \sqrt{ {61}^{2} }$

$\implies \: AC = 61$
