Thanks

is that all the information they give you ? because to me it seems like there's stuff missing and by 3 X do you mean 3 times the size?

 

[omniscience]

triangle = 180
rectangle = 360
me = cool

yea sadly this is all

it doesn't look like its 3 times

 

[Woteva636]

Let angle CBD=x
Now let angle ABE=3x
Thus angle ABE = 3 times angle CBD

No seriously, take it from someone whos completed the mathematics course (prelim and hsc) in 14 months and is now working through 4 unit, you need at least one value, other wise any angle in your diagram can equal anything less than 180 degrees.

the only thing you might want to try is getting out your protractor and measuring the angles in the book- might come out like that

Can't be proved. More information required.

You could always show a counter example which disproves it.

i think u can prove something if maybe one of those triangles are isosceles
but no u dont need any values as someone said above

hmm ok. ill double check with my teacher. thanks anyways
