i am looking to figure out ratios in geometry. If the angle of a trianle are in the extended ratio 1:3:5, find their measures
x+3x+5 = 180.
Or, \[\frac{x}{8} \times 180\]
where x is the ratio.
ok - let me try that - give me a moment
Sure.
why isn't it 5x
typo.. sorry. that's 5x/
so it should be set up as x + 3x + 5x = 180
Yes.
so then the next step is 4x + 5x = 180 and then it would be 9x = 180 and you divide it from there
Correct. u will get. x = 20. so the smallest angle is 20.
so then you subtract that from 180 and get 160 for the other angles
No. now. u know the value of two other angles. that is 3x and 5x. and you know the value of x for well. so, 3(x) = 3(20) = ? degrees/ And 5(x) = 5(20) = ? degress
so then i would get 60, 100, and 20.
Wow, you got them right. :D
:) thank you so much for ur help.
You welcome.
do u have time to help me with a quadrilateral?
idk. i will see. if i can solve them for sure.
alright. it has one angle of x+20, another of x-50, third one x+2, the last is x
post that on left please.
ok. thanks again.
