Naddika [18.5K]

Answer:

  28 m

Step-by-step explanation:

The longer side can be found using the Law of Cosines. The semi-diagonals are of length 12 and 20 m, and the angle between them facing the long side is 180° -60° = 120°.

  c^2 = a^2 +b^2 -2ab·cos(C)

  c^2 = 12^2 +20^2 -2·12·20·cos(120°) = 144 +400 +240 = 784

  c = √784 = 28

The longer side is 28 meters.

What is the sum of 6 feet 10 inches and 8 feet 9 inches?
vivado [14]
Lets first convert everything to inches.

6 feet= 12*6 = 72 + 10 = 82 inches
8 feet= 12*8 = 96+9 =  105 inches

Now add!

82+105 = 187

Now convert them back to feet.

187/12 = 15 feet

12*15 = 180

187 - 180 = 7 inches

15 feet. 7 inches. 

Final answer: B. 15 ft. 7 in.

How can you distinguish if the solution is one value, all real numbers, or no solutions?
murzikaleks [220]

Answer:

If x can only have one answer, then the solution is one value. If x can be all real numbers, then the solution is all real numbers. And if x doesn't have an answer then it has no solution.

Step-by-step explanation:

For example:

One value: 7 + x= 10 => x= 3

All real numbers: 0x=0 => x can be all real numbers

No solutions: 7x=6x => no solutions
