Answer:
1: draw a line across the circle, but not through point O
2: place the two points on the edge of the circle so that the space in between is about 1/3 of the circle. Label C and D.
3: draw two lines out from point O to the edge of the circle. 45 is half of 90. this means you can draw a 90 degree angle and divide it in half and remove the extra line. Label these E and F.
Answer:
x = 38
Step-by-step explanation:
The two angles in the picture are supplementary (sum of angles add up to 180°). That fact gives us the equation:
140 + (x + 12) = 180.
Subtracting 140 + 12 from both sides gives:
x = 38
The length of the required fence to make a square field that encloses = 5.66 km
For given question,
A farmer wants to make a square field that encloses exactly 2km² of area.
Let 'm' be the side length of the square field.
so, the area of the square field would be,
⇒ A = m²
⇒ 2 = m²
⇒ m = √2 km
We need to compute the length of the required fence.
The length of the required fence would be,
= perimeter of the square field
= 4 × m
= 4 × √2
= 5.66 km
Therefore, the length of the required fence to make a square field that encloses = 5.66 km

True because rational numbers are countable, but the irrational numbers are uncountable.
