Answer:

6748'

Step-by-step explanation:

The long diagonal is the third leg of a triangle with the given side lengths and an angle between them that is the supplement of the given angle. Its length can be found from the Law of Cosines.

a^2 = b^2 +c^2 -2bc·cos(A)

a^2 = 3473^2 +4822^2 -2·3473·4822·cos(180° -72.23°)

a^2 = 45,535,553.83

a ≈ 6748.004

The longer diagonal is about 6758 feet long.

Michael is twice as old as Ann. If 14 is added to Ann’s age and 22 is subtracted from Michael’s age, their ages will be equal. W

Digiron [165]

Answer: Michael is 72 while Ann is 36.

Step-by-step explanation: Let X represent Michael's age and Y represent Ann's. From the first sentence,

Y=2X. (eqn 1)

14+X=Y-22 (eqn 2)

X-Y=-22-14

X-Y=-36; But Y=2X.

Therefore, X-2X=-36; -X=-36; X=36. Hence, Y=2*36; Y=72.
