When solving problems like this, opposite angles will be equal to 180 when added together. So, when solving for C, you need to find x. You can do this by adding angles D and B.
3x + 9 + 2x - 4 = 180.
3x +2x + 9 - 4 = 180
5x + 5 = 180
5x + 5 - 5 = 180 - 5
5x = 175
5x/5 = 175/5
x = 35
Now, fill in x in angle A and C.
2x + 3 + C = 180
2(35) + 3 + C = 180
70 + 3 + C = 180
73 + C = 180
73 - 73 + C = 180 - 73
C = 107
The angle measure of angle C is 107. Hope this helps!

I'm not gonna give the answer because you have to solve it. Sorry. But I'll help you get it.

Step 1: solve the equation for each angle
Step 2: Add the totals from each angle
Step 3: Divide the total by 360
Step 4: You got your answer

I hope this helped! I'm sorry I answered really late.

subset to real numbers, and as you can see are not at all connected to the rest of numbers (and integers).

Natali5045456 [20]

Irrational numbers are the subset of real numbers that are not at all connected to the rest of numbers.

The subsets of real numbers are natural numbers, whole numbers, integers, rational numbers and irrational numbers.

Natural numbers are subset of whole numbers, which are subset of integers, which are subset of rational numbers. Hence, all of them are interconnected. The set of irrational numbers is the only subset of real numbers which is not associated with the rest.

For example:-

1 is a natural number, whole number, integer, rational number but not irrational number. On the other hand, $\sqrt{2}$ is an irrational number but none of the rest.
