Question

If the cos of angle x is 8 over 17 and the triangle was dilated to be two times as big as the original, what would be the value of the cos of x for the dilated triangle? Hint: Use the slash symbol ( / ) to represent the fraction bar, and enter the fraction with no spaces. (4 points)

Answer 1

Explanation:

If the original triangle's angle x has a cosine of 8/17, then the dilated triangle will have the same cosine value. The cosine of an angle remains the same under dilation since the ratio of the side adjacent to the angle to the hypotenuse remains constant. Therefore, the cosine of angle x for the dilated triangle will also be 8/17.
