The length of x to the nearest tenth is; D: 38.6 m
<h3>Trigonometric ratios</h3>The image of the triangle is missing and so i have attached it.
From the image attached, we can find the value of x by using trigonometry ratio.
We see that;
- AB = x
- AC = 10
- ∠BAC = 75°
Thus;
10/x = cos 75
10/x = 0.2588
x = 10/0.2588
x = 38.64 m
Approximating to the nearest tenth gives;
x = 38.6 m
