Well the angles should all equal 360. Since you know 90 and 160 then 360-90-160=110. Angle 2 is 90* so 110-90=20 so angle 4 is 20. Angle 2+ angle 4: 90+20=110 or C :)
Answer:
Left
Step-by-step explanation:
(x,y)
basicly it is addition add 50 cent 4 times then add the dolars to that witch will get you to 6.00 bucks add the taxes witch is 5 bucks and 50 cent so 10.50 is your ansewer
-(4/5)*(3/7)*(15/16)*(-14/9) [two negatives make one positive]
=(4*3*15*14)/(5*7*16*9) [simplify 4/16]
=(3*15*14)/(5*7*4*9)
=(3*3*14)/(7*4*9)
=(14)/(7*4)
=(2)/(4)
=1/2
C should be correct since AB and XY are in the same places
