Answer:
x=27
Step-by-step explanation:
63+90+x=180
63+90=153
180-153= 27
10) because of the alternative exterior angle theorem angle 2 is the same as angle 8 and because of the vertical angles congruence theorem angles 2 and 4 are also the same so if angle 2 is the same as both 4 and 8,
then x=5 because 4x+57 =77
subtract 57 from both sides and 4x=20
divide both sides by 4 and x equals 5
3x+40=100
subtract 40 from both sides
3x= 60
divide by 3
x=20
each Sweater cost 20
Answer:
5
Step-by-step explanation:
$4.75 + 0.3x = $6.26
0.3x = 1.51
