2:1 is the ratio
- Rach :)
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.
Answer:
4b³c⁴ + 2b⁴c³
Step-by-step explanation:
5b⁴c³ and 3b⁴c³ have the same variables. Therefore, they are like terms.
4b³c⁴ + 5b⁴c³ - 3b⁴c³
4b³c⁴ + 2b⁴c³
