Answer:
the other leg of the right triangle is, 12 cm
Step-by-step explanation:
Using Pythagoras theorem;
As per the statement:
The hypotenuse of a right triangle is 15 cm, and the shorter leg is 9 cm
⇒Hypotenuse side = 15 cm and shorter leg = 9 cm
Let x be the other or longer side
Substitute these in above formula we have;
⇒
Subtract 81 from both sides we have;
⇒ cm
therefore, the other leg of the right triangle is, 12 cm

Question 2:
Part 1. To find the how many months will take to pay the card debt, we are going to use the credit card equation:
where
is the months to pay the card
is the balance
is the monthly payment
is the interest rate in decimal form
We know from our problem that the balance of the credit card is $1,367.90 and the monthly payment is $400.00, so
and 
. To find convert the interest rate to decimal form, we are going to divide the rate by 100%
.
Now that we have all we need, lets replace the values in our credit card equation:
It will take you 3.5 months according to our calculation, but since you pay $400 each month on the due date, we can conclude that it will take you 4 months to pay off the card.
Part 2. To calculate the total amount paid including the interest, we just need to multiply the monthly payment by the number of payments.
We know from our problem that the monthly payment is $400. We also know from our previous calculations that the number of payments is 4, so lets multiply both quantities:
We can conclude that the total amount paid including interest is $1,600
