Answer 1

For the given triangle, x = 47.

Explanation:

Step 1:

In the given triangle, the angle is x°. The adjacent side has a length of 4.0 units while the hypotenuse of the triangle measures 5.9 units.

To calculate the value of x, we determine the cos of angle x where we divide the length of the adjacent side by the length of the hypotenuse.

`cos x= (adjacent side)/(hypotenuse).`

Step 2:

The length of the adjacent side = 4.0 units.

The length of the hypotenuse = 5.9 units.

`cos x = (4.0)/(5.9) , cos x = (0.6779).`

`x = cos^(-1) (0.6779) = 47.3202.`

So x° = 47.3202, rounding this off to the nearest degree we get x = 47.
