(x-5)^2 + (x-5)^2 .........
Answer:
If two polygons are similar, then the ratio of the lengths of any two corresponding sides is called the scale factor. This means that the ratio of all parts of a polygon is the same as the ratio of the sides.Jan 21, 2020
B ) sin² x = 1 - cos² x
sin² x + cos² x = 1 ( correct )
D ) cot² x = csc² x - 1
cos²x / sin²x = 1/sin²x - 1 = (1-sin²x) / sin²x = cos²x/sin²x
Identities are B ) and D).
