Answer:
x=6
Step-by-step explanation:
x+y=48
x=y-6
substitute "y-6" instead of x
x+y=48
(y+6)+y=48
y+y is equal to y
6+y=48
-6 -6
y= 42
x= 48-y
x=48-42
x=6

Answer:
- x = 95°
- y = 75°
- arc ABC = 150°
Step-by-step explanation:
The relevant relations are ...
- an inscribed angle is half the measure of the arc it intercepts
- opposite angles of an inscribed quadrilateral are supplementary
__
Using the second relation, ...
x = 180° -85° = 95°
y = 180° -105° = 75°
Using the first relation, ...
arc ABC = 2y = 2(75°) = 150°
