They are most likely 90 degrees, due to the sharing of a common side and a common vertex. They really could be anything though. If given more details, I will give a better answer. I still would like Brainliest, however.
You would use the = sign because
8+7-2^2=3^2+2
they both equal 11
Figure 1,
When 1 unit = 1 cm
Perimeter = Boundary of the figure
= 3+3+6
= 12 cm
Area of one square = side * side
= 1*1
No. of squares in the figure = 6 squares
Area = Space occupied inside the figure
= 6 cm^2
Hope it helped :)
