Question

Please show your work - Thanks!

Answer 1

c=11
b=8
a=?
So do c^2-b^2=a^2
11^2=121
8^2=64
121-64=57
And the squareroot of 57=7.5498344353
So you would roubd up to 8

Answer 2

Law of Cosines:


`a= √(b^2+c^2-2bc \cdot cos(A)) \\ b=8, \ \ c=11, \ \ \angle A=32.2^o \\ \\ a= √(8^2+11^2-2\cdot 8 \cdot 11 \cdot cos(32.2^o)) \\ a= √(64+121-176*0.8462) \\ a= √(185-148.93) \\ a= √(36.07) \approx 6`

Answer: B.
