Solutions

Chapter C, Problem 15E
To determine

To find: The length of the side x to five decimal places.

Expert Solution

Answer to Problem 15E

The length of the side is x5.73576 cm.

Explanation of Solution

Result used:

For an acute angle θ the trigonometric functions are defined as ratios of lengths of sides of a right triangle as follows.

sinθ=opphyp,cscθ=hypopp,cosθ=adjhyp,secθ=hypadj,tanθ=oppadj and cotθ=adjopp.

Calculation:

From the given figure, sin35=opphyp=x10.

Simplify the expression sin35=x10 and obtain the length of the side.

sin35=x10x=(sin35)10x5.73576

Thus, the length of the side is x5.73576 cm.
