Answer 1

The length of x to the nearest tenth is; D: 38.6 m

Trigonometric ratios

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
