In δdef, de = 11, ef = 9, and angle e = 140°. which equation correctly uses the law of cosines to solve for the third side? e2 = 112 92 − 2(11)(9)cos(140°) 112 = e2 92 − 2e(9)cos(140°) 92 = e2 112 − 2e(11)cos(140°) e = 11 9 − 2(11)(9)cos(140°)

i dont know

step-by-step explanation:

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
