Bis the midpoint of ac and d is the midpoint of ce bd = 3x, and ae = 60. find the length of ab if ac = 5x + 10. 60 30 20 10

The length of AB is 30 units.

Step-by-step explanation:

Given B is the midpoint of AC and D is the midpoint of CE.

BD = 3x, AE = 60 and  AC = 5x + 10

we have to find the value of AB.

As B is the mid point of AC and D is the mid-point of CE.

By mid-point formula, the length of line joining the mid-points of two sides of triangle is half of the parallel side.

∴

⇒

⇒

As, B is the mid-point of AC

⇒

The length of AB is 30 units.

i would say c is the best answer, hope it's right!

good luck! =)
