<u>Answer </u>
AB=21
<u>Solution </u>
In the triangle ABC two lines are parallel to side AC.In a triangle a line passing through two side and it is parallel to third side,then this line divides two side in equal ratio.
Here we take any of the parallel line, passing through AB and AC, and parallel to BC.
So we can write,=
8x+1=6x+2.5x
x=1/0.5
x=2
Therefore AB = 6x+2x+1+2x =10x+1=21
Answer:
Step-by-step explanation:
rational numbers end but irrational numbers goes on. example the value of π never ends it goes on 3.14....
1. -1 is rational
2. is irrational because it goes on forever 0.333333...... a bar on top means it never ends.
3. -4.8 is rational because it ends at 8.
4. is rational because its root of 16 is 4 which is a definite value.
5. -20/4 = -5. it is rational because its value is -5 and its a definite value.
6. 7/1239 = is indefinite becuse its value does on forever 7/1239 is 5.649715...
