ur solution is here..
hope it you☺
sorry i don't know. i am not good at maths .
edge an absolute necessity be under 90 if abc is an unfeeling triangle. when you include the measures of every one of the three points in a triangle, generally signify 180 degrees.
it doesn't make a difference how huge or little the triangle is, or how or fat it is. it's a triangle . the points dependably indicate 180 degrees.
ab = 256 so a=256/b
now proportion of a and b=128
a: b: : b: 128
