If DC=6x and DA=4x+18, find the value of x then, find AD
1 answer:
The value of x is 9 and AD is 54.
<u>Step-by-step explanation:</u>
From figure, if DC = AD, we can solve for value 'x'
DC = AD
Given:
DC = 6 x
DA = 4 x + 18
Equating the values of both, we get
6 x = 4 x + 18
6 x - 4 x = 18
2 x = 18
x = 9
So, the value of x is 9. By using this value of x, find AD
AD = 4 (9) + 18
AD = 36 + 18
AD = 54

Here’s why:
- Recall the Triangle Angle Sum Theorem: The three angles of all triangles add up to a sum of 180°.
- We will set up an equation based on this and then solve.
