Question

Right triangle ABC is shown
Which equation can be used to solve for c?
3 m
sin(509) = 3
O sin(509=
O cos(50°) =
cos(509)=

Answer 1

Answer:

$\sin (50\degree)=\frac{3}{c}$

Step-by-step explanation:

The given triangle is a right triangle with a given angle which is $50\degree$.

The side opposite to the 50 degree angle is 3 meters.

The hypotenuse is 'c' units.

We can use the sine ratio to obtain:

$\sin (50\degree)=\frac{opposite}{hypotenuse}$

$\sin (50\degree)=\frac{3}{c}$

Therefore the correct answer is A.

Answer 2

The required equation can be used to solve for c is sin 50 = 3/c

SOH CAH TOA identity

From the figure shown, the measured sides are:

• Opposite = 3m
• Hypotenuse  = c
• m<B = 50 degrees

USing the SOH CAH TOA identity

sin theta = opp/hyp

sin 50 = 3/c

Hence the required equation can be used to solve for c is sin 50 = 3/c
