Question

Find the value of x in the given

right triangle.
Enter your answer as a decimal rounded to the
nearest tenth.

Answer 1

probably 16.5

Explanation:

Answer 2

x = 12.5

Explanation:

Since the figure above is a right angled triangle we can use trigonometric ratios to find x

To find x we use cosine

cos∅ = adjacent / hypotenuse

From the question

The hypotenuse is x

The adjacent is 10

Substitute these values into the above formula and solve for x

That's

`\cos(37) = (10)/(x)`

`x \cos(37) = 10`

Divide both sides by cos 37

`x = (10)/( \cos(37) )`

x = 12.52135

We have the final answer as

x = 12.5 to the nearest tenth

Hope this helps you
