    Now, since the angle of depression is 11°, we can know the angle inside the triangle is 79°, since 11+79=90 (Forms right angle). Now, since a right angle is 90°, and since all angles in a triangle sums up to 180° (Triangle Angle Sum Theorem), the angle of elevation is 11°. Now we can use the Law of Sines to find the answer ("x" is the side we are looking for). x/sin(90) = 28/ sin(11) x = (28/sin(11))sin(90) And, using a calculator: x= 147 (rounded to the nearest foot) So the distance between the tower and the fire is 147 feet. Hope this helps! |dw:1368638375563:dw| BTW: Sorry if the drawing is a little confusing :)
