Answer:
3. X = 13.42
Step-by-step explanation:
12² + x² = 18²
144 + x² = 324
-144 -144
x² = 180
√x² = √180
x = 13.41640 (unsure of how teacher would want you to round this, probably in the hundredths)
x = 13.42
Answer:
n = s/180 +2
Step-by-step explanation:
180(n-2)=s
Distribute
180n - 360 =s
Add 360 to each side
180n -360+360 = s+360
180n = s+360
Divide each side by 180
180n/180 = s/180 + 360/180
n = s/180 +2
Well since you already completed the table, a pattern would be that the left column is twice the amount of the right column ( 30x2=60, 35x2=75,etc.)
What do you mean? At first it was 4 times as old, then it's twice her age?
159.2 or 159 1/5 If you need it as a fraction
