complete the two-column the proof by writing the appropriate reason for each statement.

given: m∠1 = m∠3

prove: m∠eba = m∠cbd

reasons (one is used twice): angle addition postulate, commutative property of addition, substitution, transitive property



1. statement: m∠1 = m∠3

1. reason: given

2. statement: m∠eba = m∠2 + m∠3

2. reason:

3. statement: m∠eba = m∠2 + m∠1

3. reason:

4. statement: m∠eba = m∠1 + m∠2

4. reason:

5. statement: m∠1 + m∠2 = m∠cbd

5. reason:

6. statement: m∠eba = m∠cbd

6. reason:

q: 92 degrees

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

positive

step-by-step explanation:

the quadrant is facing upwards

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
