A, B and C are points in the Cartesian plane. The coordinates of A are (3, -2), = (4/-3), and = (4/9). Calculate: i. The coordinates of B and C.

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

step-by-step explanation:

20%

step-by-step explanation:

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

answer is  

a.

16.1

hope you got it chief.
