Answer: Choice A) 44

cos(angle) = adjacent/hypotenuse

cos(X) = 13/18

X = arccos(13/18)

X = 43.7617 approximately

rewona [7]

Answer: Similar figures are always the same shape, but not the same size. They have equal angles but not equal side lengths. Check out a big square and a small square. They're both squares because they have four sides and four equal angles, but the sides aren't the same length.
