Answer:
a) 105 degrees
b) 75
c) 105
Step-by-step explanation:
a) 180-75 is 105 (supplementary angles)
b) same angle as kings ave and 4th street. (supplementary angles)
c) 180-75 is 105 (also vertical angle rule)
X+2y = 9 ---------eq.1
x-y =6 ----------- eq.2
x = 9 -2y (from eq. 1)
Now substitute the value of x in the second eq.2
9-2y-y =6
-3y = -3
y =1
So,
x +2 (1)= 9
x= 7
They are supplementary angles
Answer:
that's the rule
