Calculate the value of X
1 answer:
Answer:
Step-by-step explanation:
The <u><em>Triangle external angle theorem</em></u> states that :An exterior angle of a triangle is equal to the sum of the opposite interior angles. For more on this see
see the attached figure with letter to better understand the problem
step 1
Find the measure of the interior angle at B
we know that
----> by supplementary angles (form a linear pair)
step 2
Find the value of x
Applying the triangle external angle theorem
solve for x
simplify

Answer:
Third option.
Step-by-step explanation:
For this exercise you need to remember one of the properties for exponents.
There is a property called the "Negative property of exponents" which states the following:
Where
As you can observe, is the reciprocal of
In this case you have the following expression given in the exercise:
Observe the expression. As you can notice, the base "n" has a negative exponent, which is -6.
Therefore, applying the Negative property of exponents explained at the beginning of this explanation, you can simplify the expression.
Then, the simplified form of is the one shown below:
For this case we have that by definition, the volume of a cylinder is given by:
Where:
r: It is the radius of the cylinder
h: It is the height of the cylinder
We have as data, observing the figure, that they give us the radio. Then, the height is missing.
