Answer:
   sin(D) = cos(E) = (√3)/2
   cos(D) = sin(E) = 1/2
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships between trig functions and right triangle sides.
   Sin = Opposite/Hypotenuse
   Cos = Adjacent/Hypotenuse
For this diagram, this means ...
   sin(D) = cos(E) = (13√3)/26 = (√3)/2
   cos(D) = sin(E) = 13/26 = 1/2
