Answer:
12 feet
Step-by-step explanation:
By Pythagoras theorem, a²+b²=c², where c represents the diagonal and a and b represents the other sides of a right angled triangle
As a flag is a rectangle, the two triangles cut would be right angled triangles
Therefore, a²+9²=15²
a²+81=225
a²=144
a=√144
a=12 feet
I’m sorry, I wish I knew this one and I would help
Answer:
the required value of c is [ -11 -1
2 5]
I think the answer is C. X*4=-12+3
You substitute the equation and see if it works. Also, the first one that you answered is wrong.
