587. How tall is an isosceles triangle, given that its base is 30 cm long and that both of its base angles are 72 degrees? 595. To the nearest tenth of a degree, find the sizes of the acute angles in the 5-12-13 triangle and in the 9-12-15 triangle. This enables you to calculate the sizes of the angles in the 13- 14-15 triangle. Show how to do it, then invent another example of this sort.
