Sum of two angles that are supplementary = 180°
Let the smaller angle be = x


<h3>Their sum :</h3>






Using this let us find the measures of the smaller angle and bigger angle .


∴ The measure of the two angles are = 21° and 159° .
Hi there.
To start, we have to understand where the ten the place is.
Hint: it's 1 place behind the decimal point.
Now we need to know what numbers behind the tenths place make it round up or down.
If the number behind it is 4 or under, round down.
5 & up, round up.
In this case, 830.248 has 2 numbers behind the decimal, so we have to round those THEN the 2 in the tenths place.
830.25 to 830.3
Your answer is D. 830.3
I know this was lengthy, sorry. Just wanted to explain :p
B=x-5
To get x on its own you have to add 5 to both sides. This gives you:
b+5=x
or
x=b+5
Difference=subtract sum=add. just answering so you don't waste points :-)
