4. A kite is flying above the ground. a. A man has a kite on a $$15\mathrm{ft}$$ string. He measures the angle of elevation to the kite to be $$30^{?}$$. How high is the kite above the ground? b. A girl has her kite on a $$25\mathrm{ft}$$. string and measures the angle of elevation to the kite to be $$18^{?}$$. How high is her kite above the ground? (Your answer will contain a trig function since this isn't a special angle) 6. To estimate the height of a building above the ground, the angle of elevation to the top of the building is measured to be $$16^{?}.100\mathrm{ft}$$. closer to the building, the angle of elevation is $$27^{?}$$. Find the height of the building. (Hint: your answer will be in terms of $$\sin ($$ ), $$\cos (),\tan ()$$, etc. since you're not using a calculator and $$27^{?}$$ isn't a special angle) (Hint: First draw the right triangles, then set up the equations for both) Try to do this on your own, if you get stuck, go to the next page for help! Step 1: Illustrate the situation and label: (in this picture then, $$t$$ Step 2; Draw the 2 triangles separately: (you fill in the labeling below) Step 3: Now, find the $$\tan ()$$ of the angle in terms of $$x,y$$, and 100 for each triangle: (von t use a calculator!) Step 4: Solve one of your $$\tan$$ () eqns. For $$x$$ or $$y$$ and substitute this into the other eqn. (Don't use a calculator!) Step 5: You now have one equation with one unknown (either $$x$$ or $$y$$ depending on your choice in step 4. Solve for the variable. To do this, get everything with the variable on one side, factor it out, and divide by the coefficient. You now have either x or $$y$$ ! Label the $$1^{??}$$ triangle above and make sure you've indeed found the height) Step 6: Use a calculator to approximate your answer from step 5 (make sure you're in degree mode, not radian mode)
