<2 and <3 are supplementary angles...therefore they must equal 180°
since <2 = 125
you can find the measure of <3 by subtracting the measure of <2 from 180°
180 - 125 = 55° < answer
hope this helps :)

Answer:
Option 1
Step-by-step explanation:
(-5 + 2, -5 + 3) = (-3, -2)
<span>Given:
Q = 7m + 3n,
R = 11 - 2m,
S = n + 5,
T = -m - 3n + 8.
Simplify Q - [R + S] - T.
Q-(R+S)-T
=</span>7m + 3n - (11 - 2m + n + 5 ) - (-m - 3n + 8)
=7m+2m+m + 3n-n+3n -11-5-8
=10m+5n-24
