Answer:
m+n=140
Step-by-step explanation:
So the angles in a triangle always add up to 180. We already know that the first angle in the triangle is 40 degrees because it's shown in the angle below the triangle. So we have 140 degrees left since 40 is taken up. That eans m+n=140

Hi, What grade is this?
I am currently doing flvs too and could help you out.
<u>Given:</u>
Each circle has a diameter of 2 inches each.
The outer square has a side length of 4 inches and the square ABCD has a side length of 2 inches.
<u>To find:</u>
The area of the shaded region.
<u>Solution:</u>
Each circle has a diameter of 2 inches. The square ABCD is at the center of each circle so it has a side length of 1 inch.
To determine the area of the shaded region, we subtract the area of the quarter-circles in the square ABCD from the area of the square ABCD.
The area of a quarter-circle 
All the quarter-circles have a radius of 1 inch.
The area of 1 quarter-circle 
The area of 4 quarter-circles 
So the area of the quarter-circles in the square ABCD is 3.1514 square inches.
The area of a square 
The area of square ABCD 
The area of the shaded region 
The area of the shaded region is 0.8585 square inches.
