Using the formula sum of interior angles {180(n-2)}
180(15-2)=180
giving you a total of 2340 Degrees
2/3 of 13 is 8. The answer would be 8. If you want to be exact, it would be 8.66666666667.
Have a great day!

Answer:
21
Step-by-step explanation:
1 side = 6 plants (including one in the corner)
3 sides = 5 plants each
6+15 = 21

Solve linear equation two variable
Answer:
67
Step-by-step explanation:
Complementary angles add to 90 degrees
<A + <B = 90
x+10 + 3x+28 = 90
Combine like terms
4x+38 =90
Subtract 38 from each side
4x+38-38 = 90-38
4x = 52
Divide by 4
4x/4 = 52/4
x = 13
We want to find <B
<B = 3x+28
= 3(13) +28
= 39+28
=67
