Answer 5

You can set up a proportion..like this

If the leg of the little triangle is 3 units, the corresponding triangle leg will be proportional, meaning its length can double or triple. In this case the corresponding triangles leg is 6 units...so the length doubled

Answer 6

your triangles are similar :)
Given the diagram that you have, since they've given us 3 sides.
This means that ALL three sides must be in proportion.
So 6/3 = 8/4 = x/5

Therefore what would x be given that the ratios must always be the same :) ?

Answer 7

can i c the triangles first?

Answer 8

3/6 = 4/8 = 5/x

simplify...

1/2 = 5/x

Solve for x

Answer 9

First of all how in the world can u solve the awnser without seeing the triangle it can b any kind of triangle so how in the world can u solve it

Answer 12

^^Thx 2 both of u ^^

Answer 13

I am still kinda confused with the asnwer

Answer 14

To find x, we have to set up a proportion

Answer 15

basically what does
6/3 = ?
8/4 = ?
They both equal to 2 right?
So since the proportion/ratio is 2 : 1 (basically the bigger triangle, has sides which are DOUBLE in length) .
Then to find x/5, we know x has to be double the smaller side!
The smaller side is from the SMALLER triangle (so the side with length 5) so to find x, we DOUBLE 5 :)
So x = 2*5 = ?

Answer 16

10

Answer 17

Yes

Answer 18

1) Since we know 2 sides of this triangle, we will use the pythagorean theorem to solve for x.
2)Substitue the two known sides into the pythagorean theorem's formula:
A² + B² = C²
8² + 6² = x²
100 = x²

Answer 19

=10 sorry

Answer 20

So basically what they mean when they say "similar" is that all corresponding sides are in proportion. This means that one could be larger than the other or smaller, but also similar. In this case, side 3 corresponds to 6 and 4 to 8 and 5 to x
3/6 = 4/8 = 5/x
1/2 = 5/x
(5 over what equals 1/2?)
x = 10
