Question

2363°Find the length of side x.хHow do I find the answer

Answer 1

To find x, we wil simply use the trigonometric ratio:

`\cos \theta=\frac{\text{adjacent}}{\text{hypotenuse}}`

From the figure,

θ=63 adjacent=23 hypotenuse =x

substitute the values into the formula and solve for x

`\cos 63=(23)/(x)`

cross-multiply

`x\cos 63=23`

Divide both-side by cos63

`x=(23)/(\cos 63)`
`x\approx50.7`
