AD¯¯¯¯¯ , BD¯¯¯¯¯ , and CD¯¯¯¯¯ are angle bisectors of the sides of △ABC . BE=12 m and BD=20 m

1 answer:

5 0

Since triangle BDE is right, we can check it for special rules: BD is hypotenuse = 20, and BE = 12, both divisible by 4: get 5 and 3... so it's a 3-4-5 special right triangle, the 4×4 = 16 m for side DE.
Since AD bisects angle A, I think then side DG should be congruent with DG. So then
DG = 16 m

Determine the 5th term of the sequence 1, 10, 100,

balu736 [363]

To determine the 5th term you need to find the 4th. This doesn’t work for all but for this one you just add a zero at the end. So the 4th term is 1,000 and that makes the 5th term 10,000
