Answer:

x=33

Step-by-step explanation:

1) write the equation: 180=90+(x+15)+(x+9)

2) subtract 90 on both sides and add x+15 and x+9 together: 90=2x+24

3) subtract 24 from both sides: 66=2x

4) divide both sides by 2: x=33

Answer:

x = 9.6 in

Step-by-step explanation:

The scale factor is 8:10 (difference in length.) This is simplified down to 4:5.

Method 1 (easier):

4/5 × 12 = 9.6 in.

Method 2 (harder but more comprehensive):

$\frac{10}{12} \times \frac{8}{x}$

cross-multiply

$10x = 96 \\ x = 9.6$
