In ΔABC shown below, if BG = 38 what is DG? A) 19 B) 57 C) 38 D)17

Mekhanik [1.2K]

Answer:

Basically G is centeroid (intersection point all three medians) so it divides BD in the ratio of 2:1

if bd is x then 2x/3 = BG i.e 38

so GD is x/3 i.e 19

(1) In the diagram below, AC || DF|| BH || and CB || FE.

Liula [17]

Answer:

Part 1) Triangles ABC, DBG, DEF and BEH are similar

Part 2) $\frac{AB}{AC}=\frac{DE}{DF}=\frac{DB}{DG}=\frac{BE}{BH}$

Step-by-step explanation:

Part 1)

we know that

If two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

In this problem Triangles ABC, DBG, DEF and BEH are similar, because its corresponding angles are congruent by AA Similarity Theorem

Part 2)

Remember that

If two triangles are similar, then the ratio of its corresponding sides is equal

therefore

$\frac{AB}{AC}=\frac{DE}{DF}=\frac{DB}{DG}=\frac{BE}{BH}$

Answer: 5/9 yards

Step-by-step explanation:

From the question, we are informed that Jack made 9 identical bags using 5 yards of fabric.

To calculate the amount of fabric that Jack use for each bag, we have to divide 5 by 9. Thus will be:

= 5 / 9

Therefore, it means that Jack used 5/9 yards for each bag
