The answer to this problem

Ksivusya [100]

Answer:

B. $\frac{7\sqrt{2}}{34}$

Step-by-step explanation:

Cos θ = Adjacent/hypotenuse

Adjacent = 7

Hypotenuse = √(23² + 7²) = √578 = 17√2

Thus:

Cos θ = $\frac{7}{17\sqrt{2}}$

Rationalize

Cos θ = $\frac{7*\sqrt{2}}{17\sqrt{2}*\sqrt{2}}$

Cos θ = $\frac{7\sqrt{2}}{17*2}$

Cos θ = $\frac{7\sqrt{2}}{34}$

How do you simplify a fraction?

attashe74 [19]

You simplify a fraction by finding it's greatest common factor. A greatest common factor is what both numbers are divisible by. If they can both be divided by two, then you've simplified them a little bit. Keep going until you can't find a common number that can be divided by the two, and you've got your simplified fraction. For example, 10/5 = 1/2 since both 10 and 5 is divisible by 5.
