1-3=-2 so -2/8 is -1/4 so negative one fourth
Answer:
The rule is "add 5, add 10, add 20" and the rule keeps doubling.
(2x+23)+(9x-5)=95
11x+18=95
x= 95-18/11
x=7
therefore substituting value of x in the given equations of angles:
angle ABD = 2(7)+23=37°
angle DBC = 9(7)-5= 58° Answer
to verify = 37°+58°= 95° ( which was given)
and so on..
