Answer:
a=8
Step-by-step explanation:
solve for a by adding 5 on both sides
4a=32
Now divid 4 on both sides
a=8
The answer is 6.5 and what I did is I took the mixed fraction (2 2/4) and I turned It into a decimal. After I knew it was 2.5 all I had to do was use the formula A=lw to get my answer on what the width was.
Step 1: Replace the variables with numbers
A=lw
A=2(1.25)
A= 2.5 (Fraction 2 2/4)
Step 2: Use the perimeter formula (P=l+w+l+w or P=(l+w)2)
P=(l+w)2
P=(2+1.25)2
P=(3.25)2
P=6.5
Answer is 6.5 I hope this helped ^^
Answer: B) 86°
Step-by-step explanation:
The angles of a triangle always add to equal 180.
So let's call the third angle x and add the other two angles with it.
32+62+x=180
94+x=180
Now we solve for x
Subtract 94 from both sides
94-94+x=180=94
x=86
