Question

Help with angles again :X http://gyazo.com/000106abbcf81d12cae1da586f4b24ff

Answer 1

i see 2 similar scalene triangles
similar triangles are proportional to each other

this means 4 is proportional to 18
5 to 22.5
and s to 10

solve the proportion

Answer 2

I dont understand how to solve this?

Answer 3

3 ratios
s to 10, 5 to 22.5, and 4 to 18

ratios can be written as a fraction

\[\frac{s}{10},\frac{5}{22.5},\frac{4}{18}\]

similar triangles means that these fractions(ratio/ proportions) are equal to each other

\[\frac{s}{10}=\frac{5}{22.5}=\frac{4}{18}\]

so just solve for s given
\[\frac{s}{10}=\frac{4}{18}\]

Answer 4

oops , said too much and gave the answer

oh well

Answer 5

i still want to solve :D

Answer 6

how did you get that answer?

Answer 7

i just explained it

because both triangles have the same angles, this means they are similar triangles, meaning the sides of one triangle is proportional to the other

Answer 8

I hate math and im not good at it... im so confused

Answer 9

so the side between angle 1 and angle 2 are proportional to each other, the side between angle 2 and 3 are proportional to each other

this is how i got the ratios

i then changed the ratios into fractions, and you need to realize that the fractions are equal to each other

Answer 10

can you help me with another problem its proporations but not angles.?

Answer 11

make a new question

Answer 12

Which ratio forms a proportion with 12/10

Answer 13

@completeidiot ?

Answer 14

well look at the fraction 12/10, can you simplify it?

Answer 15

yea but it would be impropper

Answer 16

its already improper, nothing is wrong with improper fractions

Answer 17

http://gyazo.com/c8697e2047d2fb4f37b406b10e1bb031 idk how to draw but these are the answers and im confused with that.

Answer 18

because it would be 6 over 5

Answer 19

ok now that you gave 6/5

this is the simplest proportion you can get
now what happens if we multiply 1 to it

we still get 6/5

remember that \[1=\frac{2}{2}=\frac{3}{3}=\frac{4}{4}=\frac{10}{10}= ...\]

so what happens if we multiply
\[\frac{6}{5}*1=\frac{6}{5}*\frac{10}{10}=?\]

Answer 20

60/50?

Answer 21

then wouldnt the resulting fraction be equal to 6/5, your simplest proportion

Answer 22

and thus equal to the proportion 12/10

Answer 23

ahhh i understand

Answer 24

YAYYYYY

Answer 25

Thank you!

Answer 26

yup no prob
