1/2(5 sqrt 2)(4 sqrt 2)= 20
Answer:
>=
Step-by-step explanation:
since the shaded area is above the line y must be > or >= 1/4x-4, so the symbol must be > or >=. since the line isn't dashed, points on the line also fit the inequality meaning that the answer is >=
The length of side c would be 8.
Step-by-step explanation:
Given that,
a = 4
b = 6
cosC = -1/4
If we are given two sides and angle, the law of Cosines can be used to find the third side:

By inserting the values in the formula, we get



c = 8.
Therefore, the length of side c would be 8.
