Question
Two lines intersect as shown. What is the value of x ?
- 15
- 20
- 25
- 30
The correct answer is: 20
If two straight lines intersect at a point, we know that the opposite angles are equal.
Explanation:
Step 1 of 2:
In the diagram, the measures of two opposite angles are given by 
and 
.
Step 2 of 2:
Hence, we have
⇒ 2x = 40
⇒ x = 20
Final Answer:
The value of x is — 20.
