The triangle is an obtuse since its greater than 90 degrees but less than 180.
The answer is 2c - 72.
First complete the brackets.
46+26=72
Then subtract 4c from 2c.
4c-2c=2c
Hello,
Assume x the side of the square.
(x+7)²=4x²
==> ((x+7)-2x)((x+7)+2x)=0
==> (-x+7)(3x+7)=0
==> x=7 or x=-7/3 (to exclude since side must be positive)
Proof:
(7+7)²=196
4*49=196
3 mins* (3200 m/ 24 mins)= 400 m.
(Note that the unit cancels out)
The final answer is 400 m~
