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.
