1/6+3/8=13/24 (13/24 is the simplest form in this case)
Answer:
a)
Surface Area: 172 cm^2
Volume: 112 cm^3
b) Surface Area
c) Volume
Step-by-step explanation:
You have to find the cos of angle A, so use the Pythagorean equation and trig laws to find the other side of the triangle created by angle A. 3^2 + x^2 = 5^2. x=4. This means cos(A) = 4/5). Make both cos (A) and cos (B) have equal denominators, and add. 148/185 + 60/185 = 208/185. This answer is correct, though it doesn’t appear to be any of the answers you wrote, so either those answers are wrong or you wrote something incorrectly in the problem.
