Answer:
Step-by-step explanation:
Linear pairs
(4x + 1) + 75 = 180
Add the like terms
4x + 76 = 180
Subtract 76 from both sides,
4x = 180- 76
4x = 104
Divide both sides by 4
x = 104/4
x = 26
The angles of a quadrilateral add to 360, so we can solve for x by adding the 4 angle measures together and setting it equal to 360:
90 + 140 + (x - 10) + (x - 20) = 360
Combine like terms:
230 + 2x - 30 = 360
200 + 2x = 360
200 - (200) + 2x = 360 - (200)
2x = 160
Divide both sides by 2:
2x/(2) = 160/(2)
x = 80
He will have 220 that is how much he will have
Answer:
The side length of the small squares in inches is 2 inches
Step-by-step explanation:
Given
Area of checker board = 256 square inches
A regular checker board has 64 small squares in total that means that 256 is the area of all 64 squares. To find the area of one small square, the total area will be divided by 64
So,

Let s be the side of one small square then

Putting A =4

Taking square root on both sides

The side length of the small squares in inches is 2 inches
