4a-8=28
add 8 to both sides to start to isolate the variable (a)
-8+8 cancels each other out
28+8=36
4a=36
to completely isolate the variable divide both sides by 4
4a÷4=a
36÷4=9
a=9
Formula for the area of a circle is Pi*radius squared
So, we do Pi*2^2 which is 12.57
Answer:
Hi there the answer is 10
The 2 whole feet are 8 1/4’s and the 1/2 of a foot can get cut twice into 1/4’s.
Step-by-step explanation:
Answer:
x = 88
The measurement of the other unknown angle is = 44°
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180°
48 + x + x - 44 = 180 add like terms
4 + 2x = 180 subtract 4 from both sides
2x = 176 divide both sides by 2
x = 88
Now to find the measure of two other angles we replace x with 88
