Answers:
Common angles: ΔBGC and ΔGDC
Common sides: ΔGE and ΔAG
A common angle is a triangle that exists in two or both of the triangles.
Here, the common angles should be ΔBGC and ΔGDC.
These two angles are triangles, and they consist in both triangles.
A common side is when two angles have one vertex in the same area.
Here, we see that the common sides are ΔGE, because they intersect.
Another common side we see here is ΔAG, because they also intersect.
Hope this answer helps you!
Addition because 8-2 = 6 and then you add the 4
Divide both sides by 2 and rewrite too X^2 - x - 2 = 0. then factor and get x(x+1)-2(x+1)=0. separate them to (x+1)(x-2)=0 then you get x+1=0 and x-2=0 and solve and X equals -1 & 2
5x + 2y = 2120
x + y = 574
2y = 2120 - 5x
2y = 1148 - 2x
1148 - 2x = 2120 - 5x
-972 = -3x
x = 324
574 - 324 = y
y = 250
