when you subtract a negative number from any platitude number the equation changes to addition so you would add the value of the negative number to 1.
Use a^2 + b^2 = c^2
the triangle must be isosceles because the two angles are the same
1.2^2 + 1.2^2 = x^2
1.44 + 1.44 = x^2
2.88 = x^2
x=6√2/5
or
x ≈1.69706
5+3 = 8
8 is 100%
3/8 = 37.5%
I feel like I might be wrong haha sorry if I am
