The diagonals AC and BD of rectangle ABCD intersect at point O, the angle AOD = 120 °, AC = 4 times the root 3cm, and the length of AB is calculated

The diagonals AC and BD of rectangle ABCD intersect at point O, the angle AOD = 120 °, AC = 4 times the root 3cm, and the length of AB is calculated

AOD = 120 and AO = OD, so oad is equal to 30 degrees, so CD is equal to half of AC, so CD is equal to twice root 3, so AB is equal to CD is equal to twice root 3!

In rectangular ABCD, ∠ AOB = 120 degree, DC = 4 root sign 3cm, then s rectangular ABCD =? O point is the intersection of two diagonals △ AOB, ab = DC = 4 root sign 3,
Why is OE equal to 2

What is point e? Make it clear
You said OE is ad / 2, rectangular area = ad * AB = 16 root sign 3

It is known that ABC is a natural number, which is not equal to 0. A * 20:19 = b * 20:20 = C * 20:21. ABC is arranged in the order from large to small?

A\B=20\19
∴A＞B
B\C=21\20
∴B＞C
The order from big to small is ABC

If a △ 0.3 = B × 0.3 = C × 2 / 3 = D × 1 / 4, then what is the smallest of the four ABCD numbers?
