I think answer A should be the correct answer
Answer:
6776
Step-by-step explanation:
77
88
-----
8 times 7=56 8 times 70= 560 then add together so 616 next line 80 times 7= 560 80 times 70=5600 then add those together 6160 then add the too totals together 6160+ 616= 6776
You need to use the law of cosine:
B^2 = A^2 + C^2 - 2ACcos(b)
55^2 = 90^2 + 50^2 - 2(50)(90)cos(b)
0.841666 = cos(b)
b = 32.68
Answer:
Step-by-step explanation:
-2⁶ = -(2⁶) = -(64) = -64
(-2)×(-2)×(-2)×(-2)×(-2)×(-2) = (-2)⁶ = (-1⋅2)⁶ = (-1)⁶⋅2⁶ = 1⁶⋅2⁶ = 64
