Answer:
x = 25°
Step-by-step explanation:
Here given a straight line whose angle equals to 180°
2x + 10 + 4x + 20 = 180
group terms like this ↓
2x + 4x + 10 + 20 = 180
simplify all variables ↓
6x + 30 = 180
changing sides changes addition to subtraction ↓
6x = 180 - 30
6x = 150
changing sides changes multiplication to division ↓
x = 150/6
final answer ↓
x = 25°
Answer:
Step-by-step explanation:
if you need help let me know
Given:
A figure of a circle with secants intersecting inside the circle.
To find:
The value of x.
Solution:
According to the intersection theorem of secants, if two secants intersect each other inside the circle, then the angle on the intersection is the average of the intercepted arcs.
Using the intersection theorem of secants, we get




Therefore, the value of x is 69.
I don't know because I don't have the whole question.
