Pythagorean theorem a-squared + b-squared = c-squared 400-squared + 350-squared = c-squared 160,000 + 122,500 = c- squared 282,500 = c-squared Now take the square root of each side of the equation 531.5 = c The length of the rope is 531.5 feet
Using a right triangle formed by boat with base and top of lighthouse.Note: 15 minutes = 0.25 degreesLet d be distance the boat is from shore.tan(90−13.25)=d/175 d=175∗tan(76.75)=743.2
0 because companies A says he gets 80.000 dollars per year with a 1,000 dollars increase every year so companies B will higher have to wait 0 years to be higher than companies A
