since the altitude divides the base in half, and the vertex angle in half,
h/92.1 = cot 21°55'
1. Find the altitude of an isocles triangle having base 184.2 cm if the angle opposite the base is 68deg 44'
2. A 13.5m fire truck ladder is leaning against a wall. Find the distance d the ladder goes up the wall (above the top of the fire truck) if the ladder makes an angle of 43deg 50' with the horizontal.
