Question

how do you find the measure of an angle that is four hundred twenty less than three times its supplement?

Answer 1

(3x - 420) + x = 180

Answer 2

4x = 600

Answer 3

x = 150

Answer 4

other angle is 30

Answer 5

I was going at such a snail's pace. Fiddle you could have easily gotten this one if you wanted it.

Answer 6

I did want to. I really did ....

Answer 7

lol

Answer 8

still a bit confused about this -420 degree difference, since it's cyclic and all.

Answer 9

I think you're thinking into it way too much. Think algebra for these. We're only talking about two angles that add up to 180

Answer 10

you guys are so smart

Answer 11

I'm not smart at all

Answer 12

Fiddle might be smarter than me....

Answer 13

lol you answred it first

Answer 14

Who answers first isn't necessary a measure of smartness

Answer 15

I got here first

Answer 16

don't we need to do 420-360 = 60 or something ?

Answer 17

Why would we need to do that? You're thinking about trig and not geometry. You have to know when to separate the two.

Answer 18

maybe not...

Answer 19

you're right - you're smarter.

Answer 20

One question isn't necessarily a measure of smartness

Answer 21

I was overcomplicating it. :)

Answer 22

Well its not a race anyways :)

Answer 23

so its 3x +x =4x and then wat

Answer 24

okay so dont answer me -.-

Answer 25

Hero found the angle was 150

Answer 26

I thought I posted the solution already

Answer 27

yeah but i wanna understand how you did it. you know

Answer 28

im so confused here. i was thinking you do 3x-420+x=180

Answer 29

Check the first line of this board....

Answer 30

okay. i did i juss dont understand whwere you got 4x=600 ?

Answer 31

3x + x = 4x

180 + 420 = 600

Answer 32

ohhhhh

Answer 33

:o)
