A support flag is attached at a height of 3 m and is fixed to the ground at a distance of 1.2 m from the base calculate the length of the support.

 

And the angle between the flag pole and the ground is 90 degrees?

 

In a right triangle we know that a^2 + b^2 = c^2, where a and b are the two shortest sides, and c is the longest.

 

c = √(a^2 + b^2)

 

OK, a=3 and b=1,2.

 

c= √ (3^2 + 1,2^2)

c = √(9 +1,44)

c = √ 10,44 ≈ 3,2
