Answer:
Step-by-step explanation:
In order to find the exact length of this ladder, we can use the Pythagorean Theorem to find the length of the hypotenuse.
The Pythagorean Theorem states that , where a and b are the legs and c is the hypotenuse.
Since we know the legs (9, 12), we can solve for c (the hypotenuse).
Now that we know the length of the hypotenuse, we can solve for the cosine of the angle the ladder makes of the floor.
The cosine of the angle will be it's adjacent side divided by it's hypotenuse. We know this because of <u>SOH </u><u>CAH</u><u> TOA</u>:
Cosine: Adjacent over Hypotenuse.
The angle that the ladder makes with the floor is the one that is formed by the hypotenuse and the 9 feet leg.
The adjacent of that angle is the 9 foot side. The hypotenuse of this triangle is 15.
Therefore the cosine of this angle will be . Simplifying this down we get .
Hope this helped!
Answer:
35
Step-by-step explanation:
all you have to do is subtract each of them and they all have 35
2 x 1/4 is the same as 1/4 + 1/4
Answer:
Closing costs are fees paid at the closing of a real estate transaction. Typically home owners will pay between 2 to 5 percent of the purchase price of their home in closing fees. So, if your home cost $150,000, you might pay between $3,000-$7,000 in closing costs.
Really you only go by the denominators. if the two denominators have a same common factor than that's the one you use.
