Math Problem Statement
Find x in the figure below, rounded to one decimal place. A right triangle is given.
The first side is horizontal.
The second side of length 82 is at a right angle with the first side.
The third side is at an angle of 30° with the first side.
The triangle is split into 2 smaller triangles by a line segment connecting a vertex opposite the first side to a point on the first side at an angle 60°.
The part of the first side between the vertex of 30° and the point where the line segment ends is labeled x.
