Step-by-step explanation:
-4 between each number
Answer:
y = 65°
Step-by-step explanation:
z = 70° (corresponding angels are equal)
y + z = 135° (exterior angle theorem of a triangle)
y + 70 = 135 (substitution)
Subtract 70 from each side
y + 70 - 70 = 135 - 70
y = 65
21x - 14
Explanation:
you distribute the 7, and first multiply it by 3x to get 21x. Then you distribute the 7 and multiply it by the -2 to get -14.
Hope this helps!
