Two ponds can be seen from a tower. The angles of depression to pond A and Pond B are angle 12 degrees and angle 19 degrees respectively, form a height of 22m on the tower. The measure of the angle between the lines of sight to the ponds is angle 78 degrees. Find the distance between the ponds.

Two different linear functions are shown below with two points given from each function. use slope-intercept form or point-slope form to find the equation of each. linear function a points: (–5, –2), (–5, 7) linear function b points: (7, –5), (–2, –5) function a has: the equation of line a is: function b has: the equation of line b is:

How can constraints be used to model a real-world situation?
