grand siren I keep on getting decimals when i’m not supposed to

What have you tried

grand siren Oct 23, 2024, 2:48 AM

#

shut bloom What have you tried

equaled them to 180

shut bloom Oct 23, 2024, 2:49 AM

#

Let’s just work one term at a time.

grand siren Oct 23, 2024, 2:49 AM

#

4x-2+7y+9+90=180

#

^ thats what i did

grand siren Oct 23, 2024, 2:49 AM

#

shut bloom Let’s just work one term at a time.

okay

shut bloom Oct 23, 2024, 2:49 AM

#

Start with the term containing x

#

We can agree that that term, plus the rest of the right angle equals 90 degrees correct?

grand siren Oct 23, 2024, 2:50 AM

#

shut bloom We can agree that that term, plus the rest of the right angle equals 90 degrees ...

yes

shut bloom Oct 23, 2024, 2:51 AM

#

Great, do you notice anything about the rightmost triangle

grand siren Oct 23, 2024, 2:51 AM

#

i got 23 for x

grand siren Oct 23, 2024, 2:51 AM

#

shut bloom Great, do you notice anything about the rightmost triangle

i mean not rly im confused as hell

#

about it

#

idk if i should equal it to 60 or 90

shut bloom Oct 23, 2024, 2:52 AM

#

grand siren i mean not rly im confused as hell

It’s equilateral

shut bloom Oct 23, 2024, 2:52 AM

#

grand siren i got 23 for x

Don’t jump to any conclusions

#

What do you know about equilateral triangles? Particularly about their angles

grand siren Oct 23, 2024, 2:53 AM

#

shut bloom What do you know about equilateral triangles? Particularly about their angles

All 3 sides are equal and each of them is 60 degress

shut bloom Oct 23, 2024, 2:53 AM

#

Right

#

So can you break apart that right angle at the top into two angles equalling 90 in total?

grand siren Oct 23, 2024, 2:54 AM

#

shut bloom So can you break apart that right angle at the top into two angles equalling 90 ...

yes i think

shut bloom Oct 23, 2024, 2:54 AM

#

What are those two angles then

#

I’m asking for two numbers that add to 90

grand siren Oct 23, 2024, 2:55 AM

#

that’d be 45

shut bloom Oct 23, 2024, 2:55 AM

#

No

#

Remember what we said about the equilateral triangle angles

grand siren Oct 23, 2024, 2:55 AM

#

ohh

#

theyre 60

#

so uhm

#

maybe 60 30?

shut bloom Oct 23, 2024, 2:55 AM

#

Yes

#

Do you see the 60 and 30?

grand siren Oct 23, 2024, 2:56 AM

#

shut bloom Do you see the 60 and 30?

ig

shut bloom Oct 23, 2024, 2:56 AM

#

Yes or no?

#

If not I can draw it out

#

The 60 degree angle is in the equilateral triangle

grand siren Oct 23, 2024, 2:56 AM

#

the top one would be 30 right

shut bloom Oct 23, 2024, 2:57 AM

#

Ignore the bottom angles

#

We’re only talking about the two at the top

grand siren Oct 23, 2024, 2:57 AM

#

shut bloom We’re only talking about the two at the top

okay

#

so yeah

#

right side would be 60

#

Left side would be 30

shut bloom Oct 23, 2024, 2:58 AM

#

Yes

#

So that means that 30 is equal to the term containing x

#

What is x, then?

grand siren Oct 23, 2024, 3:01 AM

#

shut bloom So that means that 30 is equal to the term containing x

i substitute it to x right

shut bloom Oct 23, 2024, 3:01 AM

#

?

grand siren Oct 23, 2024, 3:01 AM

#

shut bloom What is x, then?

7

#

mb

shut bloom Oct 23, 2024, 3:01 AM

#

4x-2=30

grand siren Oct 23, 2024, 3:01 AM

#

8

shut bloom Oct 23, 2024, 3:01 AM

#

Right

grand siren Oct 23, 2024, 3:01 AM

#

wait how is it 8

shut bloom Oct 23, 2024, 3:01 AM

#

Are you able to solve for y now?

shut bloom Oct 23, 2024, 3:02 AM

#

grand siren wait how is it 8

4 x 8 is 32
32-2 is 30

grand siren Oct 23, 2024, 3:02 AM

#

shut bloom Do you see the 60 and 30?

u said this

#

so i thought of like 4x-2=90

#

then got 23 for x

shut bloom Oct 23, 2024, 3:02 AM

#

Which is not right

grand siren Oct 23, 2024, 3:02 AM

#

oh ok

#

so x is 8

shut bloom Oct 23, 2024, 3:02 AM

#

Yes

grand siren Oct 23, 2024, 3:03 AM

#

alr got x

shut bloom Oct 23, 2024, 3:03 AM

#

shut bloom Are you able to solve for y now?

^

grand siren Oct 23, 2024, 3:03 AM

#

now to y

grand siren Oct 23, 2024, 3:03 AM

#

shut bloom ^

I do the same thing for y?

shut bloom Oct 23, 2024, 3:04 AM

#

Not exactly because the angle where y is isn’t bifurcated (split into two)

#

You should know that there are 180 degrees in any triangle. We know the other two angles so we can solve for what the term containing y must equal

grand siren Oct 23, 2024, 3:05 AM

#

ok so i did 7y+9=30 and i got 3 for y

shut bloom Oct 23, 2024, 3:05 AM

#

Right

#

Was that a guess or did you figure out why it was equal to 30

grand siren Oct 23, 2024, 3:08 AM

#

shut bloom Was that a guess or did you figure out why it was equal to 30

not rly

#

i just thought of using given value

#

U could say it was kind of a guess

shut bloom Oct 23, 2024, 3:09 AM

#

Going forward, all of the values of these shapes are able to be solved for. Make sure to work through to exact values so you don’t ever have to guess

#

Do you want me to help you with that or are you good after finishing the porblem

grand siren Oct 23, 2024, 3:10 AM

#

i’m good

#

thanks a lot tho
