x+x+90=1802x+90=1802x=180-902x=902x/2x =90/2
x=45
9y+9y+90=180
18y+90=180
18y=180-90
18y=90
18y/18 =90/18
y=5
Answer:
Step-by-step explanation:
Let the number be x
2x - 24 = 4 *( x + 60)
2x - 24 = 4x + 240
2x - 4x = 240 + 24
-2x = 264
x = 264/ (-2)
x = (-132)
Answer:
Angle 1 and 7
Step-by-step explanation:
(see attached for reference)
In our case, the corresponding angles are:
1,5
2,6
3,7
4,8
If we look at the choices, we can see that "Angle 1 and 7" does not show up in the list above, hence this is 1, 7 are not corresponding angles.
