or in other words
3 is the opposite, and 5 is the hypotenuse.
You can use the pythagorean theorem to find the other side(adjacent)
a²+b²=c²
3²+b²=5²
9+b²=25 Subtract 9 on both sides
b²=16 Square root both sides
b = √16
b = 4
So the adjacent is 4.
tan theta = opposite/adjacent
tan theta = 3/4
To solve this problem you can apply the proccedure shown below:
1. You have that the contractor charges to tile a
patio and
to tile a
. Then, you have:
2. As you can see, the price increases each
. Therefore, based on this, if the contractor charged a customer
to tile a patio, you can calculate the difference between the first price and this one:
3. Then, if the price increases each
, the area of this patio is:
The answer is:
For 6/x+5 –5 is an excluded value of x.
So, Option D is correct answer.
Step-by-step explanation:
We need to find for which rational expression is –5 an excluded value of x.
A value of x is excluded in a rational expression if it makes the denominator of that expression equal to zero and makes the expression undefined.
In the options given below, if we put x= -5 the only option D will become undefined i.e
As we know 6/0 = undefined so, for 6/x+5 –5 is an excluded value of x.
So, Option D is correct answer.
