m ABF m&FBC = 180; m&ECD+ m ECB -
180
Given
Linear pairs are supplementary
Definition of Supplementary
Subtraction Property of Equality
40+ m2FBC = 180 ; 140+ m2ECB = 180
Same-side Interior Angles are Supplementary
Converse
Substitution Property
m FBC is supplementary to m ECB
M ABF = 40;mECD = 140
m FBC + m2ECB = 180
Addition Property of Equality
m_FBC = 140;m ECB = 40

Suppose babies born after a gestation period of 32 to 35 weeks have a mean weight of 25002500 grams and a standard deviation of 800800 grams while babies born after a gestation period of 40 weeks have a mean weight of 27002700 grams and a standard deviation of 385385 grams. if a 3232-week gestation period baby weighs 21252125 grams and a 4040-week gestation period baby weighs 23252325 grams, find the corresponding z-scores. which baby weighs lessless relative to the gestation period?

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap

Solve for b. ab + c= d b= a + old ob=allc-ch b= (d-c/a
