With both questions and show all work you. : )

< 3 and < 1 are vertical anglesvertical angles are equal

I am not good with proofsbut I can tell u that if < 2 = < 4and < 2 = 110, then < 4 = 110. And < 3 when added to < 4 will equal 180...because they form a linear pair. Therefore, < 3 = 70 (because 70 + 110 = 180)sorry, not much help on this one

 

2.4+3.2t. you get the answer by adding the ones with variables and ones without
