Find each angle measure. SEE EXAMPLE 3
19. m21
20. m22
2.
123°
1
SOWAT

Step-by-step explanation:

as , sum of both the angles on the same side of transversal is 180°

so,

Angle 2 + angle 5 = 180°

123° + angle 2 = 180°

Angle 2 = 180° - 123° = 57°

angle 2 = 57°

and

angle 1 = 123° ( Alternate Interior Angle )

hope this answer helps you dear...take care!

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
