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.
Set the measure of the exterior angle equal to the sum of the measures of the two non-adjacent interior angles. y + y + 40 = 180 2y + 40 = 180 2y = 140 y = 70. x = 70 + 40 x = 110. So, an exterior angle at the base measures 110Â°.hen, using the first theorem above, set the exterior angle (x) equal to the sum of the two non-adjacent interior angles which are 45Â° and 72Â°. x = 45 + 72 x = 117. So, an exterior angle at P measures 117Â°.
