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.

Answer:
x=-4, y=2. (-4, 2).
Step-by-step explanation:
5x+6y=-8
-2x+8y=24
-----------------
2(5x+6y)=2(-8)
5(-2x+8y)=5(24)
-----------------------
10x+12y=-16
-10x+40y=120
---------------------
52y=104
y=104/52
y=2
5x+6(2)=-8
5x+12=-8
5x=-8-12
5x=-20
x=-20/5
x=-4
Answer:
12.
Step-by-step explanation:
20% is equal to .2 as a decimal.
When the question askes 20% OF 60, we know it means multiplying.
We do .2 x 60 and get 12 as our answer.
So, 20% of 60 is 12.
Hope this helps :)
