Answer:

Step-by-step explanation:



Answer:
i think the values for a and b are: a=2 and b=1/4
I haven't got a calculator right now but substitute the values into the cosine law so:
8² = 5² + c² - (2 x 5 x c x cos58)
and then use sine law to find B
sin58/8 = sinB/5
Let share of A is 3x and B is 2x
According to question
3x + 2x = 85
x = 85/5
x = 17
Therefore A pays 51 euros
