Math Problem Statement

Solve the trig function. Enter up to the second decimal place for the answer.

sin (43) = x/9

Solution

We have the equation:

sin(43)=x9\sin(43^\circ) = \frac{x}{9}

Step 1: Solve for xx

Multiply both sides by 9:

x=9×sin(43)x = 9 \times \sin(43^\circ)

Using a calculator:

sin(43)0.6820\sin(43^\circ) \approx 0.6820

x=9×0.6820x = 9 \times 0.6820

x6.14x \approx 6.14

Final Answer:

x6.14x \approx 6.14
