Answer:
C. 31.4
Step-by-step explanation:
Given,
A right angled triangle in which one leg is of 18 unit,
Also, the angle opposite to that leg is of 35°,
We know that,
[tex]sin \theta =\frac{\text{Perpendicular}}{\text{Hypothesis}}[/tex]
Thus, we can write,
[tex]sin 35^{\circ}=\frac{18}{x}[/tex]
[tex]x sin 35^{\circ}=18[/tex] ( By cross multiplication )
[tex]x = \frac{18}{sin 35^{\circ}}=31.3820423212\approx 31.4[/tex]
Hence, the value of x is approximately 31.4.
Option C is correct.
