Answer:
90 degrees = right angle. 180 or more = straight angle. 90 degrees or more = obtuse
Step-by-step explanation:
When to lines intersect they create four angles. Each angle is opposite to another and form a pair of what are called opposite angles. Angles a and c are opposite angles. Angles b and d are opposite angles. Opposite angles are equal.
|2|, |11 ¾|, |-12|, |-20.5|
When you have absolute value, you basically remove the negative symbol.
1) x ≤ 8
2) s < 11
3) c ≤ 4.8
1) x+9-3≤14
x+6≤14
x ≤ 8
2) 44>7+s+26
44>33+s
s < 44-33
s <11
3) 6.1 - 0.3 ≥ c + 1
5.8 ≥ c + 1
c ≤ 4.8
