Answer:

134.28 m²

Step-by-step explanation:

I suppose this is an isosceles triangle

tan 75° = 2 + √3 = 3.73 = h / 6      (h: height and 6 = 12/2, 1/2 of base)

h = 6 x 3.73 = 22.38

Area = (12 x 22.38) / 2 = 134.28

Which statement about this equation is true?
Viktor [21]
The equation has no solution because:

5(n+10)=5n+10n
5n+10n=5n+10n
I subtract 5n from both sides
10n=10n
Only one side is supposed to have the variable which is n, so the equation has no solution.

Lilit [14]
A) profit/original price x100 =percentage profit

(Profit: 360-300=$60)

b) two cameras (original price): 300x2= $600
two cameras (price sold): 360x2 = $720
