Awoman measures the angle of elevation of a mountaintop as 12.0°. after walking 1.00 km closer tothe mountain on level ground, she finds the angle to be 14.0° (a) draw a picture of the problem, neglecting the height of thewoman's eyes above the ground. hint: use two triangles. (b) select variable names for the mountain height (suggestion: y) and the woman's original distance from the mountain (suggestion: x) and label the picture. (do this on paper. your instructor may ask you to turn in this work.) (c) using the labeled picture and the tangent function, write two trigonometric equations relating the two selected variables. (dothis on paper. your instructor may ask you to turn in this work.) (d) find the height y of the mountain by first solving one equation for x and substituting the result into the other equation.
