SpletAn angle measured from the horizontal up is called an angle of elevation. An angle measured from the horizontal down is called an angle of depression. Example The two equal sides of an isosceles triangle are each 24 cm. If each of the two equal angles measures 52 , find the length of the base and the altitude. Solution C 2 24 x x 2 x cm 19 2 SpletTo find the shoreline angle, use a ruler to draw a straight line along the terrace tread that extends beneath the terrace riser (clim). Draw another straight line down the riser until it …
