Question

How do I solve this question?

Answer 1

x = 7

Explanation:

We can identify the figure formed by 2 radii, (6x - 3), and (3x + 18) as a kite because it is a quadrilateral symmetric around a center line.

The radii sides are congruent, and therefore, the other two sides must be congruent as well. So, we can solve for x by equation (6x - 3) and (3x + 18).

`6x - 3= 3x + 18`

↓ subtracting 3x from both sides

`3x - 3= 18`

↓ adding 3 to both sides

`3x = 18 + 3`

`3x = 21`

↓ dividing both sides by 3

`\boxed{x = 7}`
