Question

help anyone ? please

Answer 1

$\bold{Solution}$

$\bold{Sine law}$

A, B, C are angle and a,b,c are side

When we divide side a by the sine of angle A

it is equal to side b divided by the sine of angle B,

and also equal to side c divided by the sine of angle C

$\frac{a}{sina} = \frac{b}{sinb} = \frac{c}{sinc}$

=>

$\frac{x}{sina} = \frac{10}{sinb} = \frac{11}{sin51}$

=>

$sinb = 10 \times \frac{sin51}{11}$

$sinb = \frac{sin51}{1.1}$

sin 51= 0.670

$sinb = \frac{0.670}{1.1}$

$sinb = 60.90$

$b = {sin}^{ - 1} 60.90$
