What is the recursive rule for an=3n+5? a1=8;an=an−1+5

a1=5;an=an−1+3

a1=3;an=an−1+5

a1=8;an=an−1+3

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
