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.

A dilated triangle concerns sides only, otherwise the shape will change.

A dilated triangle x 2 times, only the sides will be affected & the new triangle will be similar to the previous one (always the 3 angles of the 1st will be respectively equal to the 2nd). Then THE ANGLE WILL REMAIN THE SAME

and cos x = 8/17

 the value of angle would change as the triangles will be similar.

so, 8/17 is the answer
