Hello we know that the triangles are proportional so they have the same ratio
the unknown side is 21 because of this.
18/6=3/1
for each 1 unit in the bottom triangle there are 3 in the top
9×3=21

The ▲TSU ~ ▲KLJ
|KS| and |KL| are similar.
|TU| and |KJ| are similar.

1st/2nd = 1st/2nd
18/6= x/9
3/1= x/9

9 is nine times more 1
so the x must be nine times more as well.
3.9=27

Hope it helps!

Since BC is parallel to DE, triangles ABC and ADE are similar. What are the lengths of the unknown sides?
NikAS [45]

Answer:

C

Step-by-step explanation:

Step 1: find BC

Given Triangles ABC and ADE are similar,

\frac{AB}{AD} = \frac{BC}{DE}

BC = \frac{AB}{AD} x DE

= \frac{8}{8 + 4} x 9

= 6 cm

Step 2: use Pythagorean theorem to find AC and / or AE

Consider triangle ABC,

by Pythagorean theorem,

AB² + BC² = AC²

AC² = 6² + 8² = 100

AC = √100 = 10 (answer... we can see that C is the only one with AC=10.

Step 3: Verify.. even though we know that it is C because AC  = 10,  you can verify that the ansewer is correct by finding CE and confirming that CE=5

By using similar triangles ABC and ADE,

AC/AE = AB / AD

AE = AD/AB x AC = 12/8 x 10 = 15

CE = AE - AC = 15 - 10 = 5 (answer confirmed)

Whats the absolute vaule of -1 1/3​
Phoenix [80]

Answer:

1 1/3

Step-by-step explanation:

Absolute values are how far away it is from 0, so it is always positive. It is always the positive number of itself, so absolute values of negative numbers are the opposite, and the absolute value of positive numbers and just the same numbers.
