Question

which expression can be used to find the value of x?

• (sin 29°)(sin 42°)
____________
9

• 9(sin 42°)
_______
sin 29°


• 9(sin 29°)(sin 42°)


• 9(sin 29°)
________
sin 42°

Answer 1

Answer:

• 9(sin 42°)

_______

sin 29°

Step-by-step explanation:

Answer 2

The value of x is calculated by the sine rule is 9(sin 42°)/sin 29°. Then the correct option is B.

What is trigonometry?

Trigonometry deals with the relationship between the sides and angles of a triangle.

We know that the sine rule is given as

$\rm \dfrac{a}{sin A} =\dfrac{b}{sin B}=\dfrac{c}{sin C}$

Then put the values and we have

$\begin{aligned} \rm \dfrac{x}{sin 42^o} &= \rm \dfrac{9}{sin 29^o}\\\\\\\rm x &= \rm \dfrac{9*sin 42^o}{sin 29^o} \end{aligned}$
