Answer:
a) 1/2; reduction
b) 5/4; enlargement
Step-by-step explanation:
In each case, the scale factor is CP'/CP. When it is more than 1, the dilation is an enlargement.
Even before you run the numbers, you can tell if it is an enlargement or not. If the dilated figure is larger, P is closer to C than is P'. If P' is closer to C, then it is a reduction.
a) CP'/CP = (4-2)/4 = 2/4 = 1/2 . . . . a reduction
__
b) CP'/CP = 25/20 = 5/4 . . . . an enlargement

Answer:
![\angle YPR = 42^o](https://tex.z-dn.net/?f=%5Cangle%20YPR%20%3D%2042%5Eo)
Step-by-step explanation:
Its given:
![\angle FPY = 90^o \\ \angle YPR + \angle FPR = 90^0 \\ 4p + 80 + 5p + 82 = 90^o \\ 9p = -72^o \\ p = -8 \\ \\ \angle YPR = 5(-8) + 82 = 42^o](https://tex.z-dn.net/?f=%5Cangle%20FPY%20%3D%2090%5Eo%20%5C%5C%20%5Cangle%20YPR%20%2B%20%5Cangle%20FPR%20%3D%2090%5E0%20%5C%5C%204p%20%2B%2080%20%2B%205p%20%2B%2082%20%3D%2090%5Eo%20%5C%5C%209p%20%3D%20-72%5Eo%20%5C%5C%20p%20%3D%20-8%20%5C%5C%20%5C%5C%20%5Cangle%20YPR%20%3D%205%28-8%29%20%2B%2082%20%3D%2042%5Eo)
