Answer:
X  = 5 unit
Step-by-step explanation:
Given as , ABC is a Triangle ,
AC extended to through C to D
∠BAC = 6x + 10
∠ABC = 6x - 10
∠BCD = ∠ 8x + 20
When c extended to D then , ∠BCD is an external angle
∵ <u>External angle = Sum of opposite internal angles</u>
Or ,∠BCD = ∠BAC + ∠ABC
Or, ∠ 8x + 20 = 6x + 10 + 6x - 10
Or, ∠ 8x + 20 = 12x
 Or, 12x - 8x = 20
∴ 4x = 20
So, x =  = 5
 = 5
Hence the value of X = 5  unit  Answer

The blue point on the number line is 5 units away from zero, which is: 5.
<h3>What is a Number Line?</h3>
A number line is an arrangement of numbers from point zero, on both sides of the starting point, which is zero.
In the number line given, the blue point is 5 units away from the starting point, zero.
Therefore, the blue point is 5 on the number line.
