you will need to use the law of cosines since this picture does not indicate that this is a right triangle
c^2 = a^2 + b^2 – 2ab cos C,
16^2 = 17^2+8^2 -2*17*8*cosC
256=289-272cosC
-33=-272cosC
33/272 = cosC
cos^-1 (33/272)=C taking the inverse cos
C=83.0 (to the nearest tenth)
b^2 = a^2 + c^2 – 2ac cos B,
8^2 = 17^2 +16^2 -2*17*16cosB
64=289-544cosB
-225=-544cosB
225/544=cosB
cos^(-1) =B
B=65.5
A=180-83-65.6
A=31.4
Answer: 300
Step-by-step explanation: you first multiply 5 and 6 that is 30. Then you multiply the product by 100 that is 300
1) y= -5
2) m = -1
3) k = 3
4) y = -5
Step-by-step explanation:
1) 
Solving:

2) ![8(-1+m)+3 = 2 [m-5 1/2]\\](https://tex.z-dn.net/?f=8%28-1%2Bm%29%2B3%20%3D%202%20%5Bm-5%201%2F2%5D%5C%5C)
Solving:
3)
(Note: Considering 8(12-k)=3(k+21) instead of 8(12-k)=3(k=k+21))
Solving:

4) 
Solving:
