You would use the POINT SLOPE FORMULA and the Slope Formula

which is as follows ...

slope formula : \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

point slope formula:  y - y_{1} = m(x - x_{1} )

Suppose a triangle has two sides of length 3 and 4 and that the angle between these two sides is 60 degrees . What is the length
Darya [45]

Answer:

  √13 ≈ 3.6056

Step-by-step explanation:

The Law of Cosines can be used to figure this. If the third side is "c", then it tells you ...

  c² = a² + b² - 2ab·cos(C)

  c² = 3² + 4² -2(3)(4)(cos(60°)) = 9 + 16 - 24(1/2) = 13

  c = √13 ≈ 3.6056

The length of the third side is √13, about 3.6056.
