Answer:
80 degrees
Step-by-step explanation:
To start, use the fact that the largest angle is the opposite of the longest side. Now, use the Law of Cosines (a^2 = b^2 + c^2 - 2bc cos A), where a is the longest side and A is its opposite, and b and c are the other sides. Plug the values in to get 1681 = 1962 - 1638 cos A, or cos A = 281 / 1638. Now, use a calculator to get that A is approximately 80.12 degrees, or 80 degrees.
Answer:
x = -27
Step-by-step explanation:
2/3 x + 17 = -1
Subtract 17 from each side
2/3 x + 17-17 = -1-17
2/3x = -18
Multiply each side by 3/2
3/2 * 2/3x = -18*3/2
x = -27
