Answer:
D. 12
Step-by-step explanation:
Based on the Angle Bisector theorem, the opposite sides of ∆ABC are divided into proportional segments alongside the two other sides of the triangle, as BD bisects the <ABC. This implies that:
AB/AD = CB/CD
Substitute
AB/8 = 6/4
Cross multiply
AB*4 = 6*8
AB*4 = 48
AB = 48/4
AB = 12
For the each of them simply substitute for x in each equation to see if you get the corresponding y , it doesnt really get any more straightforward than this
Answer:
- To a whole number: Add the numbers in the ratio together
- To a fraction: Each number in the ratio would become a numerator in a fraction
I hope this helps!
