(3y+40)+(3x-70)=180
3y+3x-30=180
3y+3x=210
3(y+x)=210
y+x=70
x=70-y
meanwhile 180-120=x therefore x=60
therefore
60=70-y y=10
so x=60 y=10
Answer:
Step-by-step explanation:
If an angle measures x degrees, the measure of its supplement is (180-x) degrees.
This means that x-62.4 = 180-x, meaning that x=121.2.
So, the angles are 121.2 and 58.8 degrees.
Its false cause its not the set of all numbers
You will get a number with a decimal: 22.360679775.
Answer:
4,5,27
Problem:
Boris chose three different numbers.
The sum of the three numbers is 36.
One of the numbers is a perfect cube.
The other two numbers are factors of 20.
Step-by-step explanation:
Let's pretend those numbers are:
.
We are given the sum is 36:
.
One of our numbers is a perfect cube.
where
is an integer.
The other two numbers are factors of 20.
and
where
.

From here I would just try to find numbers that satisfy the conditions using trial and error.






So I have found a triple that works:

The numbers in ascending order is:
