Answer:
cos ∅ = 15/17
Step-by-step explanation:
hypotenuse² = 15² +8² = 225 + 64 = 289
hypotenuse = √289 = 17
cos ∅ = 15/17 =
C. The vertexes are the same. The functions' vertex (h,k) values were not altered, just a (stretch/compress).
Figure out the radius then divide it by two. The diameter is one end of a circle to another.
