Answer:
12.6 ft
Step-by-step explanation:
Trig functions relate the sides and angles in a right triangle. Here, we're given an angle and an adjacent side, and we're asked to find the hypotenuse. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
cos(50°) = DE/CD = (8.1 ft)/CD
Solving for CD, we find ...
CD = (8.1 ft)/cos(50°) ≈ 12.601 ft
The length of CD is about 12.6 feet.

Answer:
351cm³
step by step explanation:
Volume of the prism:
=[1/2×(a+b)×h]×l
=[1/2×(5+8)×6]×9
=(1/2×13×6)×9
=(6.5×6)×9
=39×9
=351cm³
