Find the image of point (-3,5) under enlargement with centre at(-2,-6), with scale factor 4
Answers: 2
Answer from: Quest
(sin 42)/31. = sinx)/37
sinx = 37 (sin42)/31
= 37× 0.66/31 = 0.787
x= 51.9
other angle opposite to y = 180-51.9-42
= 180- 93.9 =86.1
so
sin42)/31 = sin 86.1)/y
0.021 = 0.997 /y
y= 0.997/0.021 =47.47
