Answer:
Step-by-step explanation:
Let a be the length of the altitude, then from the given triangles, applying the basic proportionality theorem, we get

⇒
⇒
⇒
⇒
Thus, the length of altitude is: 12 cm.
Now, 
⇒
⇒
Also, 
⇒
⇒
Thus, the lengths of the legs of this triangle are 14.83 and 20 cm.
Answer:
Cristiano will have enough money to buy bike in 9 weeks.
Step-by-step explanation:
Given:
Cost of the bike = $189
Money saved = $99
Money saving each week = $10
We need to find the number of weeks will he have money to buy bike.
Solution:
Let the number of weeks be 'x'.
Now we can say that;
Money saved plus money saving each week multiplied by number of weeks is equal to cost of the bike.
framing in equation form we get;

Subtracting both side by 99 using subtraction property of equality we get;

Dividing both side by 10 using division property of equality we get;

Hence Cristiano will have enough money to buy bike in 9 weeks.
Answer:
Answer C
