PLEASE HELP At this point, the plane started descending. As the plan turned, its altitude dropped from 3060 feet to 1650 feet above ground level, calculate the angle of descent if the plane traveled 0.5 miles (c). Note the difference in altitude is 1390 feet

In triangle abc, the length of side ab is 12 cm, the length of side bc is 5 cm, and the length of side ca is 9 cm. find the measure of angle a using the law of cosines.

Find two consexutive odd integers such that the sum of their square is 650

Answer this two poles, ab and ed, are fixed to the ground with the of ropes ac and ec, as shown: two right triangles abc and edc have a common vertex c. angle abc and edc are right angles. ab is labeled 13 feet, ac is labeled 15 feet, ec is labeled 10 feet, and ed is labeled 4 feet. what is the approximate distance, in feet, between the two poles? 11.14 feet16.65 feet14.35 feet15.59 feet
