In the cube abcd-a1b1c1d1, e is the middle point of a1d1 and F is the middle point of a1c1. The angle between AE and CF is obtained

As shown in the figure, if b1bcc1 is extended one time backward and M is the midpoint of C1q, then AE ‖ = cm
Let AB = 2, then cm = 5, CF = 6, MF = 5, & nbsp; from cosine theorem cos ∠ MCF = 3 / √ 30
The angle between AE and CF = arccos3 / √ 30 ≈ 56 ° 47 ′ 21 ″

In the triangle ABC, am is the middle line of BC, n is any point on am, passing through point n, making de parallel to BC, respectively intersecting with AB and AC at point D, e, proving DN = ne
In the triangle ABC, am is the middle line of BC, n is any point on am, passing through point n, making de parallel to BC, respectively intersecting with AB and AC at point D, e, proving DN = ne

It is easy to get △ adn ∽ ABM. △ AEN ∽ ACM
∴DN/BM=AN/AM NE/MC=AN/AM
∴DN/BM=NE/MC
Because m is the midpoint of BC
∴DN=NE

The sum of numerator and denominator of a simplest fraction is 86. If 9 is subtracted from both numerator and denominator, the resulting fraction is 89, then the original fraction is 89______ ．

The sum of the numerator denominator of the new fraction is: 86-9 × 2 = 68; the denominator of the original number is: 68 × 9 ^ (9 + 8) + 9, = 612 ^ 17 + 9, = 36 + 9, = 45; the numerator of the original number is: 86-45 = 41; the original fraction is: 4145
