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:
3x + 2 = 50
16
Step-by-step explanation:
According to the given situation, the equation to determine the number of friends is shown below:-
We assume the number of friends is x
50 - 3x = 2
-3x = -48
3x = 48
x = 16
So, the equation is
3x + 2 = 50
and the number of friends is 16
Therefore, the equation to determine the number of friends we just solved the above equation.
1 centimetre=0.1 decimetre
therefore the answer is 2.5 decimetres.
