Ответ:
8 units
Step-by-step explanation:
Given
Hypotenuse CF = 10
m<C = 29degrees
m<D = 90degrees
m<F = 180 - (29+90)
m<F = 180 - 119
m<F = 61degrees
Since the side facing <F is CD, then;
Opposite = CD
using the SOH CAH TOA identity
sin 61 = opp/hyp
sin61 = CD/10
CD = 10sin61
CD = 10(0.8746)
CD = 8.746
Hence the length of CD is 8 units
