ANSWER :

ANSWER : a = 4; b = 8; c = 11

ANSWER : a = 4; b = 8; c = 11

ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C)

ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C)

***ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C) 112 = 42 + 82 - 248 * cos(C)***

***ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C) 112 = 42 + 82 - 248 * cos(C)121 = 16 + 64 - 64 * cos(C) Sqare values***

ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C) 112 = 42 + 82 - 248 * cos(C)121 = 16 + 64 - 64 * cos(C) Sqare values121 - 16 - 64 = -64 * cos(C) Subtract a and b from both sides

ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C) 112 = 42 + 82 - 248 * cos(C)121 = 16 + 64 - 64 * cos(C) Sqare values121 - 16 - 64 = -64 * cos(C) Subtract a and b from both sides41 = -64 * cos(C)

ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C) 112 = 42 + 82 - 248 * cos(C)121 = 16 + 64 - 64 * cos(C) Sqare values121 - 16 - 64 = -64 * cos(C) Subtract a and b from both sides41 = -64 * cos(C) 41 / -64 = cos(C) Divide both sides by -2ab

ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C) 112 = 42 + 82 - 248 * cos(C)121 = 16 + 64 - 64 * cos(C) Sqare values121 - 16 - 64 = -64 * cos(C) Subtract a and b from both sides41 = -64 * cos(C) 41 / -64 = cos(C) Divide both sides by -2abC = cos-1(-0.641) Inv cos

ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C) 112 = 42 + 82 - 248 * cos(C)121 = 16 + 64 - 64 * cos(C) Sqare values121 - 16 - 64 = -64 * cos(C) Subtract a and b from both sides41 = -64 * cos(C) 41 / -64 = cos(C) Divide both sides by -2abC = cos-1(-0.641) Inv cos

ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C) 112 = 42 + 82 - 248 * cos(C)121 = 16 + 64 - 64 * cos(C) Sqare values121 - 16 - 64 = -64 * cos(C) Subtract a and b from both sides41 = -64 * cos(C) 41 / -64 = cos(C) Divide both sides by -2abC = cos-1(-0.641) Inv cos

ANSWER : a = 4; b = 8; c = 11 c2 = a2 + b2 - 2ab cos(C) 112 = 42 + 82 - 248 * cos(C)121 = 16 + 64 - 64 * cos(C) Sqare values121 - 16 - 64 = -64 * cos(C) Subtract a and b from both sides41 = -64 * cos(C) 41 / -64 = cos(C) Divide both sides by -2abC = cos-1(-0.641) Inv cos Repeat for 1 more angle then use Pythag for the third
