Given: < B and C form a linear pair, ZA = 2B, and m_A = 120° Select the reason that best supports Statement 2 in the given proof. Prove: m_C = 60° ° A. Definition of Congruency B. Linear Pair Postulate Statement: 1. LA ELB 2. m A = mB 3. M_A = 120° 4. 120º = m_B 5. ZB and C form a linear pair 6. m2B + m2 = 180° Reason: : 1. Given 2.[?] 3. Given 4. Substitution 5. Given C. Reflexive Property D. Subtraction Property of Equality 6. Linear Pair Postulate 7. Substitution 8. 7. 120° + m2 = 180° 8. m C = 60°

replication and blocking

step-by-step explanation:

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
