Answer:

60

Explanation:

b = the hypotenuse of a right angle triangle

a = the adjacent side.

R is being defined by the cosine

cos(R) = adjacent / hypotenuse

adjacent = 16* sqrt(2)

hypotenuse = 32*sqrt(2)

Cos(R) = 16*sqrt(2) / 32*sqrt(2) sqrt(2) cancels.

cos(R) = 1/2

R = cos-1(1/2)

R = 60 degrees.
