35+55+a=180
90+x=180
-90. -90
A= 90
Answer:
There are 10 alive, and it depends on what the question meant by "How many of them are left?", because they all might be still in the bowl.
Step-by-step explanation:
So to find the answer you need to use SOHCAHTOA
Sine= Opposite/ Adjacent
Cosine= Adjacent/Hypotenuse
Tan = opposite/adjacent
angle ADC is 60 so to find the length of line ABC we would use the angle and the line DC.
We would use Tan with opposite over adjacent
Tan 60 = opp. / 5 root 3
opp. = 15
so that is the length of the entire thing, all you need to do now is find the length of the single line of BC which we can use the same equation with just Tan 30 now.
Tan 30 = opp. / 5 root 3
opp. = 5
next you need to take the entire ABC length and subtract the length of BC to get AB
15-5 = 10
so the answer would be C
I'm assuming you're trying to solve for r.
First divide a to both sides
Now you have
= a - r
Subtract a to both sides.
And then divide by -1 to both sides.
Now your equation is -
+ a = r
Answer:
5.26 < 5.4
Step-by-step explanation:
This is generally true, but is also shown by the number line.
