Mike notices that the adverts in old newspaper give the the prices for goods as mixed numbers. The price for coffee is given as one twelfth of a pound and the price of sugar one and one third pounds. (A) Calculate the total cost of the coffee and sugar in pounds​

2 x 503

step-by-step explanation:

its 1006

answer: cos [   arcsin (3/5) - arccos (1/2) ] =

step-by-step explanation: × = 3/5 = 0.6--> x = 36.87 and x = 180 - 36.87 = 143.13 deg

cos y = 1/2 --> y = +- 60 deg a. cos (x - y) = cos (143.13 - 60) = cos 83,13  

=

0.12

b. cos (36.87 - 60) = cos (-23.23) = 0.92

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.

the answer to this is a. a^2 + b^2 = c^2
