Find the point,
Movides segment AB into a ratio of 23 if A is at (013) and B is at (200)

the formula of a slope:

we have the points (-2, 7) and (2, 3). substitute:

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

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