Answer:
64.94
Step-by-step explanation:
(49.95•30%)+49.95
Answer:
x=8°
y=29°
Step-by-step explanation:
vertically opposite angles are equal
so 5x+9°=y+20°
therefore 5x-y=11°
Alternate angles are equal
so 4x+17°=y+20°
therefore 4x-y=3°
equation 1....... 5x-y=11°
equation 2......4x-y=3°
using elimination method x=8°
y=29°
Since both y’s are negative you can combine them to make -6y=1 then you divide -6 on each Side to get y=6
Any set of 3 points is "coplanar".
