Answer:
B) 100
Step-by-step explanation:
All 3 interior angles of a triangle add up to 180 so:
x + 25 + 55 = 180
x + 80 = 180
x = 180 - 80
x = 100
< 1 and < 2......adjacent angles...because they have a common side and a comon vertex
< 1 and < 2.....complimentary angles....because when added, they equal 90
answer : (0,1) (3,2) (6,3)
572 rounded to the nearest 10 is 570 and 572 rounded to nearest 100 is 600.
