Answer:
1. a = 5, b = 8
2. d = 2
Step-by-step explanation:
1. The sum of adjacent angle is 180 degree
115 + 8b +1 = 180
8b = 180 -116
b = 8
Similarly
14a - 5 + 115 = 180
14a = 180 -110
14a = 70
a = 14
2. Intersecting diagonals divide each other into equal halves
3d + 5 = 5d + 1
2d = 4
d = 2

x+2x+1=13
3x+1=13
3x=13-1
3x=12
x=12:3

The denominators should have the same number.
