Help me please. For these problems I need to solve for x and find the measures of the angles given I’m so stumped on these 3

When only separate discreet points are graphed it is called?

Find the solutions for a triangle with a =16, c =12, and b = 63º

Proceed as in example 3 in section 6.1 to rewrite the given expression using a single power series whose general term involves xk. ∞ n(n − 1)cnxn − 2 n = 2 − 4 ∞ ncnxn n = 1 + ∞ cnxn n = 0
