Question

Right triangle ABC is shown.

Answer 1

Answer:

The required equation which can be used to solve for the value of c is given by :

$\bf\sin 50=\frac{3}{c}$

Step-by-step explanation:

For better understanding of the solution, see the attached figure :

AC = 3 meter

CB = a meter

BA = c meter

m∠ABC = 50°

Now, to find the value of c.

In right angle triangle right angled at C, we need to find the length of hypotenuse, so using the sine rule in the ΔABC

$\implies \sin\theta=\frac{Perpendicular}{Hypotenuse}\\\\\implies \sin 50=\frac{3}{c}$

Hence, the required equation which can be used to solve for the value of c is given by :

$\bf\sin 50=\frac{3}{c}$
