Tell whether the statement is always, sometimes, or never true. explain. 1. if x and y are supplementary angles, then x is obtuse. 2. if x and y are right angles, then x and y are supplementary angles. 3. if x and y are complementary angles, then y is a right angle. needed asap if possible, : )

1. sometimes

2. never true

3. sometimes

step-by-step explanation:

these are pretty self explanatory if you know what supp right and com angles are

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
