Polygon ABCDE rotates 52° about the origin to create polygon
A'B'C'D'É'. If mZBCD= 31°, what is mZB'C'D' ?

125 yards

step-by-step explanation:

i take 75 plus 50.

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.

the first sequence is an arithmetic sequence.
