The Law of Cosines features the 3 side lengths of a triangle, plus the measure of the angle opposite one of those sides.


We want angle x, which is opposite the side of length 39.


Then: a^2 = b^2 - 2ab cos C becomes 39^2 = 36^2 + 59^2 - 2(36)(59)cos x


or 1521 = 3481 + 1296 - 2(36)(59) cos x


Subtract (3481+1296) from both sides: 1521 - 4777 = -4248cos x

-3256 = -4248cos x

-3256

Then: cosx = --------------- = 0.766

-4248


Solving for x: x = arccos -0.766 = 0.698 radian, or 40 degrees (answer)

5 = 1 and 5 in a fraction and w
vovangra [49]
What we want to do first is isolate the variable. To do this we need to multiply each side by 5 to remove the fraction

5 * 5 = 5* \frac{1}{5} w
    Simplify the right side
5 * \frac{1}{5} w = 1w
    Now simplify the left side
5 * 5 = 25
    Then we get...
25 = w

There's your answer!
