Answer:
6.7
Step-by-step explanation:
Here, we can apply cosine law,
We the plug in values:
and solve that CB is around 6.7
A = 115 + 1/2 (p + s)
you subtract 115 from both sides, and you get
A - 115 = 1/2 (p + s)
now you multiply by 2 on both sides, and you get
(A - 115) * 2 = p + s NOTE: I DISTRIBUTED 2 IN THE FOLLOWING EQUATION
now you subtract p on both sides to get s by itself and you get
2A - 230 - p = s
so the final answer is .......
you subtract 115 from both sides, and you get
A - 115 = 1/2 (p + s)
now you multiply by 2 on both sides, and you get
(A - 115) * 2 = p + s NOTE: I DISTRIBUTED 2 IN THE FOLLOWING EQUATION
now you subtract p on both sides to get s by itself and you get
2A - 230 - p = s
