Answer:184ft²
Step-by-step explanation:2(5×10)+2(4×6/2)+(6×10)
100+24+60=184
PLEASE MARK ME AS BRAINLIEST!!!
(f + g)(x) = f(x) + g(x) therefore (f + g)(4) = f(4) + g(4)
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.
