Answer:
G = 110
Explanation:
The figure is a quadrilateral, which means the sum of the angles is 360
We know that angle E and G are the same
100+40 + E + G =360
Combine like terms
140 +E+G = 360
Replace E with G since we are looking for G
140 + G + G = 360
140 +2G = 360
Subtract 140 from each side
140-140+2G=360-140
2G = 220
Divide by 2
2G/2 =220/2
G = 110
