The angle of elevation from the second search team to the climber is 22°. Observing the two triangles in The formula for the area of an oblique triangle is given byThis is equivalent to one-half of the product of two sides and the sine of their included angle.Find the area of a triangle with sides[latex]\,a=90,b=52,\,[/latex]and angle[latex]\,\gamma =102°.\,[/latex]Round the area to the nearest integer.Find the area of the triangle given[latex]\,\beta =42°,\,\,a=7.2\,\text{ft},\,\,c=3.4\,\text{ft}.\,[/latex]Round the area to the nearest tenth.about[latex]\,8.2\,\,\text{square}\,\text{feet}[/latex]The more we study trigonometric applications, the more we discover that the applications are countless. Find the area of the park if, along one road, the park measures 180 feet, and along the other road, the park measures 215 feet.Brian’s house is on a corner lot. If the man and woman are 20 feet apart, how far is the street light from the tip of the shadow of each person?
$$ Let’s see how this statement is derived by considering the triangle shown in Using the right triangle relationships, we know that[latex]\,\mathrm{sin}\,\alpha =\frac{h}{b}\,[/latex]and[latex]\,\mathrm{sin}\,\beta =\frac{h}{a}.\,\,[/latex]Solving both equations for[latex]\,h\,[/latex]gives two different expressions for[latex]\,h.
