Webh = d*tan(theta1) = 250 * tan(15.45) = 63.31 m so the vertical distance from point 250 meters down the tunnel to the surface of the mountain is 63.31 meters. 9. WebMar 14, 2014 · If you pick a point on the circle then the slope will be its y coordinate over its x coordinate, i.e. y/x. So at point (1, 0) at 0° then the tan = y/x = 0/1 = 0. At 45° or pi/4, we are at an x, y of (√2/2, √2/2) …
