Answer:
x=45
Step-by-step explanation:
An entire triangle is 180 degrees and you already know that one angle is 90 degrees. 180 - 90 is 90. Now you have the equation 2x=90.
You then divide each side by 2 to get the x by itself which leaves you with x=45.
A probability experiment is conducted in which the sample space of the experiment is S={1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.

Answer:
The answer is "
"
Step-by-step explanation:
Given set:

In the above-given set, there are 8 elements and 12 possible outcomes so, the equation is:


by using the general addition Rule:


The expression is 2 - m/4 + 10, when m = 12, the value is 9. Then the correct option is C.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Two less than the quotient of a number and four, increased by ten.
That can be written as in the form of m will be

If the value of m is 12, then we have

Thus, the expression is 2 - m/4 + 10, when m = 12, the value is 9. Then the correct option is C.
