Answer:
1. acute angle, 2.right angle, 3.obtuse angle
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
130 + y = 180 {linear pair}
y = 180 - 130
y = 50°
3x - 6 +8x + 4 + 50 = 180 {Angle sum property of triangle}
3x + 8x - 6 + 4 + 50 = 180 {Combine like terms}
11x + 48 = 180
11x = 180 - 48
11x = 132
x = 132/11
x = 12°
25 and -12 because when you subtract 12 from 25 you will get 13 and when you multiply 25 by -12 you will get -300
