Find <_6 if m <_8 = 120 degrees
IceJOKER [234]

Answer:

120 degrees

Step-by-step explanation:

Since p is parallel to q, <6 and <8 are congruent because of corresponding angles.

m<8=m<6

120=m<6

Since m<8 is 120, and the two angles are congruent, the m<6 is also 120 degrees.

Given: 3x+1=-14 Prove: x=-5

Statements    Reasons

1. 3x+1=-14     Given

2. 3x=-15          Subtraction Property of equality  ( since we subtract 1 from                         each side)

3. X=-5          Division Property  ( since we divide each side by 3)
