Find the missing parts of the triangle. (Find angles to the nearest hundredth of a degree.)

a = 7.5

b = 13.3

c = 16.0

, ,

Step-by-step explanation:

The first two angle can be determined by the Law of the Cosine:

The sum of internal angles of a triangle must be equal to 180°. Then:

Which satisfies the condition described.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
