I think 3 would be the answer if not I'm sorry
Im pretty sure it’s the last one.
Answer:
Step-by-step explanation:
Sum of external angles = 360
2x + 2x + x + 20 +x +40 = 360
6x + 60 = 360
6x = 360 - 60
6x = 300
x = 300/6
x = 50
The correct answer is D

Answer:
See explanation
Step-by-step explanation:
Given


Required
Find x
The question is incomplete, as the relationship between both angles is not given
(1) If they are supplementary, then


Collect like terms


Divide both sides by 7

(2) If they are complementary, then


Collect like terms


Divide both sides by 7

(3) If they are vertically opposite angles, then

So, we have:

Collect like terms
