Answer:
See Explanation
Step-by-step explanation:
The measure of angle X would be 50 degrees because 65 degrees is already labeled and B would also be 65 degrees so 65 + 65 = 130, and finally subtract 180 - 130 to get the final measure of angle X: 50 degrees
To multiply: 
The multiplication of 
is attached into the figure.
Now, since, 
Then, 
The correct name is the right triangle
The 5x5 square grid has 6 , 2 x 2 subgrids and the least value of n for which you can be certain that it will have a 2 x 2 subgrid of grey squares is 12.
<h3>What is a Square ?</h3>
A square is a polygon with four sides and all the sides are equal and parallel and all the angle value is 90 degree.
(a) The 5x5 square grid has 6 , 2 x 2 subgrids.
(b) the least value of n for which you can be certain that it will have a 2 x 2 subgrid of grey squares is 12
as it can be understood from the figure 2 that only the last square doesn't have a pair and the rest all does
more than that will be extra but 12 will be enough to make all the grey squares of 2 x 2 subgrid .
