The measure of Angle E, the angle of elevation from point A to point B, is ( 3 x plus 1 ). The measure of Angle D, the angle of depression from point B to point A, is 2 ( x plus 8 ) Find the measure of each angle.
Let E----------------> angle of elevation D----------------> angle of depression we know that E=(3x+1) D=2(x+8) remember that angle of elevation is equals to angle of depression------> by alternate angles then E=D (3x+1)=2(x+8)-----------> 3x+1=2x+16----------> 3x-2x=16-1-----> x=15 E=3*15+1-------> 46° D=2*15+16-----> 46°
the answer is the measure of angle of elevation and angle of depression is 46°
