Answer:
wha tis the qeustion
Step-by-step explanation:
Given ,
7/3 = n/21
We need to find the value of n,
Cross multiplying,we get
3n = 21 x 7
=> 3n = 147
=> n = 147/3
=> n = 49 is the required answer
X=8.
Following the similarity statement, we know that AC is to DF as BC is to EF. The ratio would be:
24/(x-2) = 20/5
Cross multiply:
24*5 = 20(x-2)
Use the distributive property:
120 = 20x - 40
Add 40 to both sides:
120+40 = 20x - 40 + 40
160 = 20x
Divide both sides by 20:
160/20 = 20x/20
8 = x
