The message is supposed to say HAPPYNEWYEAR.
we are given with a triangle with the sides 6 ft, 21 ft, 23 ft. although it follows the rule of triangles that state that no side of the triangle exceeds the sum of the lengths of two other sides, this does not follow Pythagorean theorem: 23^2-21^2 = 88 which is not equal to 6^2 or 36. This is not a right triangle, hence. Hope this helps!
Its 7.
Have a good day :)
Answer:
hello :
the perimeter is : p = 2(w + l )
p = 2(4.5+6) = 21 millim
Well, apologies if this is wrong but in my opinion, I think it's that The angles do not change. This is because the angles are alright staying in the same place. I don't understand much about angles but it makes the most sense to me.
