find the measure of angle a round your answer to the nearest hundredth

33.56
39.81
50.19
56.44

by pythagorean formula, the last side is √(61)

by cos rule

cos A

A = 39.81

answer: c. is your answer

step-by-step explanation: get me a black leather coat

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
