Logic question:
how would i demonstrate the validity of the following argument using either the reduction ad absurdum or conditional proof technique?
(g • p) → k, e → z, ~p → ~ z, g → (e v l), therefore, (g • ~l) → k

what is the approximate angle of acb if abc is 25cm and the length of segment bc is 15

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
