Tall fescue (Lolium arundinaceum) seeds germinate in seven to 12 days. Hard fescue (Festuca longifolia) and red fescue (Festuca rubra) seeds take seven to 14 days. Plant 7 to 9 pounds of annual ryegrass seed or 6 to 9 pounds of perennial ryegrass per 1,000 square feet in the fall.
More About Base Angle Theorem. 1  Base angles of an isosceles triangle are equal.  Converse of the base angle theorem is also true, i.e. if two angles of a triangle are congruent, the sides opposite to these angles are congruent.
So if a base angle in an isosceles triangle measured 58 degrees, we could plug that into our formula to determine the measure of the apex angle: M = 180 - (2 * 58). M = 180 - 116. M = 64. The measure of the triangle's apex angle is 64 degrees.
