Answer:
- x = 1.4
- BD = 8.8
- BC = 2.7
- CD = 6.1
Explanation:
Assuming an additive relation, we have ...
BC +CD = BD
Solution
Substituting the given relations, we can find x:
(4x -2.9) +(5x -0.9) = 7x -1
2x = 2.8 . . . . . . . . . add 3.8-7x to both sides
x = 1.4
Then the segment values are ...
BD = 7(1.4) -1 = 8.8
BC = 4(1.4) -2.9 = 2.7
CD = 5(1.4) -0.9 = 6.1
