The terminal side of θ passes through the point (10, 6). What is the exact value of cos θ in simplified form?
seraphim [82]

Answer:

\frac{5\sqrt{34}}{34}

Step-by-step explanation:

The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = \sqrt{a^{2} + b^{2}  }.

In the equation you'd write that as r = \sqrt{10^{2} + 6^{2} which can be simplified to \sqrt{136.

You end up with \frac{10}{\sqrt{136} } and you simplify this by doing \frac{10 }{\sqrt{136} } * \frac{\sqrt{136} }{\sqrt{136} }, ending with the result of \frac{5\sqrt{34}}{\sqrt{34} }.

(I also got this answer right on the test.)
