# Problem: A woman wishing to know the height of a mountain measures the angle of elevation of the mountaintop as 12.0°. After walking 1.00 km closer to the mountain on level ground she finds the angle to be 14.0°. (a) Draw a picture of the problem neglecting the height of the woman's eyes above the ground. Hint: Use two triangles. (b) Using the symbol y to represent the mountain height and the symbol x to represent the woman's original distance from the mountain label the picture. (c) Using the labeled picture write two trigonometric equations relating the two selected variables. (d) Find the height y.
