Answer:

Step-by-step explanation:
This triangle has a small square, which represents a right angle. Therefore, we can use the Pythagorean Theorem.

Where <em>a</em> and <em>b </em> are the legs of the triangle and <em>c</em> is the hypotenuse.
In this triangle, 7 and √15 are the legs, because these sides make up the right angle. The unknown side is the hypotenuse, because it is opposite the right angle. So, we know two values:

Substitute these values into the formula.

Solve the exponents.


Add.

Since we are solving for c, we must isolate the variable. It is being squared and the inverse of a square is the square root. Take the square root of both sides.

The third side length is <u>8.</u>

Answer:
$378,000
Step-by-step explanation:
The computation of the bad debt expense for the year is shown below:
Bad debt expense = Outstanding account receivable × estimated percentage given - credit balance of allowance for doubtful account
= $6,500,000 × 0.06 - $12,000
= $390,000 - $12,000
= $378,000
We simply deduct the credit balance from the estimated balance so that the correct amount could arrive
You just need to know that all sides need to have the same measurement because it is a equilateral triangle.
385=15n+85
385-85=15n
300=15n
300/15=n
20=n
