The arc is 4 right,
And the whole circle has a perimeter of 20.
If you do 20/4, you get a total of 5 of those pink arcs that fit in the circle.
A circle has 360 degrees, so if you do 360/5 = 72 and That’s your answer. I hope you understand my logic, if you don’t I can clear some things up....?
ANSWER:
72 degrees
I am not sure if you wrote a repeating decimal with the line next to the 0.025 so comment if you need it. If it wasn't repeating it would be simply 1/40 if there is no repeating and you only want 0.025 is a fraction in simplest form.
Multiply first equation by -5 and 2nd by 2, add them
15x+20y=-100
<u>2x-20y=32 +</u>
17x+0y=-68
17x=-68
divide both sides by 17
x=-4
the x value is -4
2/5
Step-by-step explanation:
4 ÷ 2 = 2
10 ÷ 2 = 5
Answer is 2/5
