Consider these statements. 1. ZA and ZB are complementary.
2. If two angles are complementary, then the sum of the
measures of their angles is 90°.
Which conclusion can be drawn from these statements using
deductive reasoning?
What’s the answer ?

A

Step-by-step explanation:

the logic is as follows:

if a then b and if b then c, then a then c

since we know angle a and b complementary, and we know if they are complementary they add up to 90 degrees, we know angle a and b add up to 90 degress

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
