Answer:
x=30⁰
Step-by-step explanation:
4x-55+3x+25=180
7x-30=180
7x=210
x=30⁰
Proof
3(30)+25=115
4(30)-55=65
115+65=180⁰

Step-by-step explanation:
the distance from (0,0) to (3,2) would be (3,2). Flip that and you get (2,3).
the distance from (1,5) to (4,7) is (3,2). Also flip that and you get (2,3)
the distance from (-2,-2) from (4,2) is (6,4). flip that and you get (4,6). break it down and you'll get (2,3)
