Explanation:
1. 605 feet = 7260 inches
15:7260 = 1:484 = Circle number 2
2. 8/12 = 2/3
10/15=2/3
14/21 = 2/3
The correct similarity statement is Circle C, ABC is similar to DEF
3. 2.5/1.5 = 25/15=5/3
8/4.8=80/48=10/6=5/3
These 2 statements show that the quadrilaterals are similar.
Similarity statement = Circle 2 = JKML is similar to PQRS
4. ABC is similar to ACE, which is similar to CBE, therefore, the correct answer is Circle 3.
5. Using the similarity of triangle ADB and BDC, 5/y = 3/x = 4/3.
5/y = 4/3, 15 = 4y, y = 15/4
3/x = 4/3, 9 = 4x, x = 9/4
The correct answer is Option 2
6. Does your diagram mean that Angle PQS and SQR are equal?
7. You can use AA similarity to prove they are equal. (They both have a 72 degree angle, and the opposite angles of the intersection of the lines are equal.
