Question

In Exercises 2 and 3, find the value of x that makes PQR ~JKL.

Answer 1

2. 4

3. 9

Explanation:

2. 4 ~ 8

3 ~ x + 2

x + 1 ~ 10

8 / 4 = 2

2 (3) = x + 2

6 = x + 2

- 2 - 2

x = 4

2 (x + 1) = 10

/ 2 / 2

x + 1 = 5

- 1 - 1

x = 4

3. 9 ~ 13.5

x + 1 ~ 15

13.5 / 9 = 1.5

1.5 (x + 1) = 15

/ 1.5 / 1.5

x + 1 = 10

- 1 - 1

x = 9
