< 3 is supplement of < 4, and m< 3=57 find m< 4

m<4 = 123

Step-by-step explanation:

find thing you need to understand is what is supplementary angles.

if the sum of two angles is 180 degree than it is said to be supplementary.

so

m<3 + m<4 =180

57 + m<4 = 180

m<4 = 180 - 57

m<4 = 123

answer: idk
