To keep it from falling, we nailed a 6-foot strap into the ground 4 feet from the base of the tron, We allached the strap to the tree 3% feet above the ground. What was the angle the tree was leaning? Webb1 x = We know that the angle 6. π has sine equal to 1/2, so only angles with reference angle 6. π. can be solutions. Also sine is positive in Quadrants I and II so the solutions are the angles in the first and second quadrants. with reference angle 6. π. This leads to the general solutions π π. π π 2 k , 2 k 6. 5 6. for any integer k.
