Answer:
1040
Step-by-step explanation:
Circumference of the Circle: 439.82
Add that to the length of the rectangle time two: 439.82+(300x2)
That will give you the perimeter around the entire track:
439.82+(300x2)
439.82+600
1039.82
Rounded that is: 1040
<em>Hope this Helps :)</em>
Due to the Triangle Angle Sum Theorem, we know that the sum of the interior angles of a triangle is 180 degrees.
90 + 2x - 2 + x + 5 = 180 degrees.
Combine like terms.
3x + 93 = 180
Subtract 93 from both sides.
3x = 87
Divide both sides by 3
x = 29
