Answer:
A)
P=2x+2\pi rP=2x+2πr
B)
x=\frac{1}{2}(P-2\pi r)x=
2
1
(P−2πr)
C)
x\approx173\text{ feet}x≈173 feet
Step-by-step explanation:
So, the track is composed of a rectangle and two semicircles.
The side length of the rectangle is x, and the radius of the semicircles is r.
Part A)
The perimeter is simply the length around the figure.
We can see that the perimeter will be equivalent to two times x plus two times the circumference of the semi-circles.
Answer:
409.2
x − 2
Step-by-step explanation:
Answer:
divide 10 by both sides so your answer is 8
Step-by-step explanation:
Set up the equation:
x=(3x-70)
0=2x-70
2x=70
x=35
Now to find LMN we plug it back in:
3(35)-70=35
Final answer: 35 degrees
