<span>We have to calculate the length of the missing side.
Use the Pythagorean theorem:

a^2+32^2=58^2\\\\a^2+1024=3364\ \ \ |-1024\\\\a^2=2340\to a=\sqrt{2340}\\\\a=\sqrt{36\cdot65}\\\\a=6\sqrt{65}

\cos x=\dfrac{6\sqrt{65}}{58}=\dfrac{3\sqrt{65}}{29}

I think. Your answers to choice are wrong.

Solve five and three sixths minus two and one third.
CaHeK987 [17]

Answer:

3 3/18

Step-by-step explanation:

5 3/6-2 1/3

We first need to turn our mixed numbers into fractions by multiplying the while number by the denominator, then adding the numerator. When we do this, 5 3/6 turns into 33/6 and 2 1/3 turns into 7/3. Now we have this:

33/6-7/3

Now we need to find the Least common multiple of the denominators in order to find our common denominator, which in this case is 6. 33/6 already has a denominator of 6, so we do not need to do anything to it. To give a denominator of 6 to 7/3, however, we must multiply by 2, giving us this:

33/6-14/6

Now we can subtract the numerators.

19/6

To turn this back into a mixed number, we divide 19 by 6, which gives us 3 with a remainder of 1. Therefore, our answer is 3 1/6. This is an equivalent fraction to the fourth answer, 3 3/18.

HTH :)

gogolik [260]

f(x) = 7x-5

 find f(-10)

 replace x with -10

 so you have 7(-10)-5

7*-10=-70 - 5 = -75

 so f(-10) = -75
