Answer:
2√5 ≈ 4.47214
Step-by-step explanation:
You can draw a triangle with corner points (-1,2); (1,2) and (-1,-2), and the distance will be the hypotenuse, use pythagoras to solve:
√(2²+4²) = √20 = 2√5
Answer:
4.472 units
Step-by-step explanation:
1-(-1)=1+1=2
2-(-2)=2+2=4
2²+4²=c²
4+16=c²
20=c²
c=√20
c=4.472 units

Answer:
Step-by-step explanation:
Goven the length of the field = 110m
Width = 80m
The length of the diagonal is expressed using the pythagoras theorem;
d² = l² + w²
d² = 110² + 80²
d² = 12100 + 6400
d² = 18500
d = √18500
d = 136.01
Hence the players have to run 136.01m diagonally
Answer:
Step-by-step explanation:
Lets x =measure of arc JK
37 = 1/2 (45 + x)
74 = 45 + x
74 - 45 = x
29 = x
or
x = 29
answer
B. 29
