The value of X would be 9
Angle a is directly opposite from a 40 degree angle, so a=40. Then we can find b since the sum of the angles of all triangles is 180 and there is a right angle in there along with angle a:


Last, to find c we just notice that it is supplementary with an angle of measure 65, so:


So our angles are a=40, b=50, c=115.
Answer:
The expression will be simplified into 
Step-by-step explanation:
It's like addition, when you multiply exponents that are on the same bases as each other.
To round to the nearest hundred, look at the tens place value. It is a 5. Remember that if the number is 5 or higher, round up, if 4 and lower, round down.
6254 rounded to the nearest hundred is 6300
6300 is your answer
