Answer: Scroll down
Explanation:
Image one:
1. Using SAS similarity, we can find 48/60 = 20/ML
1200 = 48 ML
ML = 1200/48 = 25 = Circle one
2. 24/x+5 = 54/36
x = 11
3. 20/36 is not equal to 24/42, so the triangles are not similar, = D
Image two:
1. 21/17.5 = 18/15 = 1.2
PQR is similar to D
2. D because then the ratios of the sides are all 3:1, and thats SSS similarity.
Image three:
1. Given
2. Property of cross multiplication
3. Given
4. SAS
