A person in a small boat sights the top of a 40-foot lighthouse found on a cliff. The angle of elevation to the top of the lighthouse is 50.2 degrees. If the distance from the base of the cliff to the boat is 75 feet,what is the height of the cliff?

let the height of the cliff be h feet to the top of the lighthouse tan 50.2 = (h+40)/75 h+ 40 = 75tan 50.2 h = 75tan 50.2 - 40 = ........

A line contains the points (0, -2) and (1,3). Another line graphed in the same coordinate plane contains the points (3, -1) and (-2,0). Based on the slope of these lines, are they parallel, perpendicular or neither?

(0,-2),(1,3). (3,-1),(-2,0). m1 = (3-(-2)) / (1-0) = 5/1 = 5. m2 = (0-(-1)) / (-2-3) = 1/-5 = -1/5. mi and m2 are negative reciprocals of each other.Therefore, the lines are perpendicular.
