Answer:
The selected graph is correct
Step-by-step explanation:
Answer:
X = 100
Y= 140
Step-by-step explanation:
The angle of y is same with 140, x u just need to 180= 2(180-140)+x
Answer:
x=20; vertical angles theorem
Step-by-step explanation:
hi! we can use the vertical angles theorem for this. vertical angles are congruent to each other, meaning they are the same amount of degrees. so, we can set 2x+10 and 50 equal to each other.
2x+10=50
2x=40
x=20
x=20 because of the vertical angles theorem.
Try subtracting first there were 10 then four were sold I don't know what happens after but thats what I know
