Please please please help me with these questions I’m having trouble with geometry :(

see explanation

Step-by-step explanation:

1. given ∠ 1 = 120° then ∠ 3 = 120° ( vertical angles )

2. given ∠ 2 = 13° then ∠ 4 = 13° ( vertical angles )

3.

∠ 2 and ∠ 3 are adjacent angles and are supplementary, thus

∠ 2 = 180° - ∠ 3 = 180° - 110° = 70°

4.

∠ 4 and ∠ 1 are adjacent angles and supplementary, thus

∠ 1 = 180° - ∠ 4 = 180° - 65° = 115°

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
