Answer Happy

A woman wishing to know the height of a mountain measures the angle of elevation of the mountaintop as e, = 12.5°. After walking d = 0.85 km closer to the mountain on level ground, she finds the angle to be e, = 13.6º. (a) Draw a picture of the problem, neglecting the height of the woman's eyes above the ground. Hint: Use two triangles. Choose File No file chosen This answer has not been graded yet. (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. Choose File No file chosen This answer has not been graded yet. (c) Using the labeled picture, complete the two trigonometric equations relating the two selected variables. (Use the following as necessary: x.) y = *tan(12.5°) *tan(13.6°) (d) Find the height y. km
