Answer:
50
Step-by-step explanation:
since all angles add up to 180
and since this is a right triangle the square in the corner is 90 degrees
so 40+90+x=180
130+x=180
subtract 130 from both sides
130-130+x=180-130
x=50
Hope that helps :)
You would plug the 2 into the place of the n. 50+100(2). the answer is 250.

The answer is:
The correct option is:
C) 
<h2>
Why?</h2>
To solve the problem, we need to remember the product of powers with the same base property, the property is defined by the following relation:

If we are multiplying two or more powers with the same base, we must keep the base and add/subtract the exponents.
So, we are given the expression:

We can see that both powers have the same base (4), so solving we have:

Hence, we have that the correct option is:
C) 
Have a nice day!
Answer:
Take a fixed gap and draw 180 degree arc of equal size on each side.
The compass size should be the same for the whole process, be careful.
Make 90 degrees angle for both side and cross two arcs from each 90 degrees. The point thus obtained should be produced vertically towards the line AB. The point on the line segment is the line bisector.
