Find the value of z
z= 131°
x= 6.5
y= 9.4
To find the value of z, we can use the Law of Cosines:
c^2 = a^2 + b^2 - 2ab*cos(C)
Here, a = x = 6.5, b = y = 9.4, and C = z = 131°.
c^2 = (6.5)^2 + (9.4)^2 - 2(6.5)(9.4)*cos(131°)
c^2 ≈ 42.25 + 88.36 - 122.2*(-0.601815023) ≈ 157.61
Taking the square root of both sides:
c ≈ √157.61 ≈ 12.56
Therefore, z ≈ 12.56.
To find the value of z, we need to use the given values of x, y, and z.
Since z is given in degrees, and x and y are numbers, it is unclear how they are related or what calculations need to be done to find z. Can you please provide more information or context about the problem?
