Honestly, this is just a bash.
test test test.
Did you get it?
If so, nice!
So we have 12 liters in the end.
First, we can set acid percentage to 10%
a=.1
And we also have 12-a as the full solution at 100%
Soo..
.1a+12-x=.3(12)
solve the rest
:D
I got the same for 1
1) the angles in this ratio 3:7 add up to 90. So 90/(10)=9, 9*3=27, 9*7=63. 63 is your answer, and checking, we have 63+27=90
If you can't tell even at this point...
i really don't know what to say
try using a bit more brainpower.
Maybe try simplifying your equation you have?
Wait why is that?
OooOOh because we're on a clock? okie
How did you come to that?
is there like a rule?
But isn't it asking for the shaded?
Im really bad at trig
don trust me but
We have Pythagorean theorem, 36+x=100, x=64, AC=8.
Now, cos A would then be i THINK AC/BC, which is 8/10. Or, exactly 0.800000000.
