2 tens is 20 1 one is 1
so 21 times 10 is 210
Answer:The formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height. The formula A=lw is used to find the area of the three rectangular side faces, where A = area, l = length, and w = width.
Plugging in the measurements that are given in the net, calculate the area of each face. Remember to use the correct area formula for the triangles
The sum of the interior angles of a triangle is 180 degrees. Therefore, if we add up all of these angles, they will equal 180.
82 + 55 + x = 180
137 + x = 180
x = 43 degrees
Hope this helps!! :)
75
Reduction of 12
3 x 4 = 12
Increase of 10
5 x 2 = 10
75 - 12 = 63
63 + 10 = 73
Change = 2 inches (75 - 73)
(5,7) because when you divide that’s the answer you get
