The figure shown is a square with a triangular hole cut into one side .The ratio of the height H of the triangle to a side length of the square Is 3 to 4 ratio of the base of the triangle to the side length of the square is 1 to 2 if the area of the square 16 in.² what is the area of the shaded part of the Square

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle

A’b’c’ are the coordinates to the new location of the transformed triangle abc. find the distance between the coordinates points to use for your calculations.

A: 0.26 would be the answer
