Answer:
The lenght of one side= 6
Step-by-step explanation:
The cost of fencing around the field for one meter = 15
The total cost = 360
The perimeter = 360 / 15 = 24 m
The lenght of one side= 6
( p = 4S)
so .... (s = p /4 )
24 = 4s
so .... s = 24/4 = 6
I hope it's right !!!!!
'is' in mathematics means the equal sign
'of' in mathematics means the multiplication sign
the number can be any variable you chose it to be

Divide both sides by 28

Multiply by 100 on both sides to isolate 'x'
14 is 28% of 200
4r + 5 = 3 is not an algebraic expression because expressions are basically equations but WITHOUT answers. In this equation, 3 is shown as the answer, which makes it an equation, not an expression.
Hope this helps! Please correct me if I'm wrong! :D
Answer:
m∠4 = 40°
Step-by-step explanation:
Using the vertical angle theorem we can find that...
m∠6 ≅ m∠7


Using this, we know that angle 6 and 8 are supplementary so...
m∠6 + m∠8 = 180°
140° + m∠8 = 180°
m∠8 = 40°
Then, we can use the corresponding angle theorem to find that...
m∠8 ≅ m∠4
m∠4 = 40°
