For the given triangle, x = 47.

Step-by-step 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.

Step 2:

The length of the adjacent side = 4.0 units.

The length of the hypotenuse = 5.9 units.

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

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
