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.

sheraz12345 · Answer

now we have to dilate this triangle

anonymous · Answer

so 17 is the hypotenuse

sheraz12345 · Answer

Yes because as we know 

cos = base / hyp 
So in the question it is given 8/17 hence 17 is hyp

anonymous · Answer

ok now i don't know what else to do

sheraz12345 · Answer

Lets see what @Abmon98 has for us ..

I think now we will just double the values and get our answer .. bUt i think thats not right

abmon98 · Answer

Similar triangles have the same shape but may have different sizes. Same ratio but with a scale factor of k so it would stay the same

sheraz12345 · Answer

Ahh yes ratio will remain same even if u double it
