Answer:
x = 10
Step-by-step explanation:
Since two angles lie on line M, we know that their sum will be equal to 180. Since we know one the their angles, we subtract 136 from 180 and get 44.
We also know that the sum of all a triangle interior angle together equal 180. We all ready have two of those angles so we can now find the third.
44 plus 90 equals 134.
180 minus 134 equals 46. So now we know the measurement of the last angle.
Now to we have to solve for x.
We know that 4x+6 equal 46, since they both represent the angle of angle L.
Once you solve 4x+6=46, you will get x = 10.
Answer: x = 10
125.
16 (10 and 6) divided by 100 is 6.25. Times two is 12.5. (For 200) times 10 for 10 marbles.
The answer to both the subparts using the circumference of the circle is:
- (A) If an athlete runs around the track then the athlete traveled (168.78+73π)m.
- (B) The area of green space on the track is 0.64m².
<h3>What is a length of a rectangle?</h3>
- The length of the rectangle is traditionally thought of as being the longer of these two dimensions, however, when the rectangle is depicted standing on the ground, the vertical side is typically referred to as the length.
What is a circumference of a circle?
- The distance along a circle's perimeter is referred to as its circumference.
- Circumference of the circle formula: C = 2πr.
Here,
(A) A circuit of a racetrack is equal to the sum of the two lengths of a rectangle and the circumference of the circle.
We get:
- = 84.39 * 2 + 73π
- = (168.78 + 73π)m
(B) Let the area of the green space of the track is x.
Then, calculate as follows:
- 168.78 + xπ = 400
- x = (400 - 168.78)/π
- x = 73.64m
So, the inner circle of distance is 73.64 - 73 = 0.64m.
Therefore, the answer to both the subparts using the circumference of the circle is:
- (A) If an athlete runs around the track then the athlete traveled (168.78+73π)m.
- (B) The area of green space on the track is 0.64m².
