Question 262023: Problem:
SLTM is a rhombus
measure of angle LST=11x-24
measure of angle TSM=3x+8
find x and the measure of each of the angles above
I don't understand how this can work because these angles are on the diagonal inside the rhombus not on one of the vertices.

Thanks
Given two points (x1, y1) and (x2, y2), derive the equation of the line that passes through those two points and write
it in the form y = mx + b. This is called the slope-intercept form of the equation of the line because the two parameters m and b
represent the slope and y-intercept of the line.
