Solve the triangle. a = 21°, c = 105°, c = 5

Two angles are complementary. the larger angle is 36 more than the smaller angle. what is the measure of the larger angle?

What is the sum of the geometric series in which a1 = 7, r = 3, and an = 1,701? hint: cap s sub n equals start fraction a sub one left parenthesis one minus r to the power of n end power right parenthesis over one minus r end fraction comma r ≠ 1, where a1 is the first term and r is the common ratio
