Can someone please help me with this?

x=41

Step-by-step explanation:

Please see attached picture for full solution.

x = 41 degrees

Step-by-step explanation:

The given triangle is a right angle triangle.

From the given right angle triangle,

the hypotenuse of the right angle triangle is 5.3

With m∠x as the reference angle, the adjacent side of the right angle triangle is 4.0

The unknown side represents the opposite side of the right angle triangle.

To determine m∠x, we would apply

the cosine trigonometric ratio.

Cos θ, = adjacent side/hypotenuse. Therefore,

Cos x = 4/5.3 = 0.7547

x = Cos^-1(0.7547)

x = 41 degrees
