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

If triangle ABC undergoes a dilation of scale factor 3 centered at the origin, the coordinate of the image of point B is known to be option D. (6,9).
<h3>What is the dilation about?</h3>The term Dilation is known to be a kind of a transformation, that is used to change the size of an object.
Note that Point B has coordinates of (2, 3)
So the Dilation factor 3 will alter the coordinates as:
(2*3, 3*3)
= (6, 9)
Hence, If triangle ABC undergoes a dilation of scale factor 3 centered at the origin, the coordinate of the image of point B is known to be option D. (6,9).
