Answer:
fourth option
Step-by-step explanation:
Given
3x < - 9 ( divide both sides by 3 )
x < - 3
solution set is { x | x < - 3 }
Answer: 130
In order to solve for <4, you need to know that supplementary angles add up to 180°.
<3 = 50
180 - 50
130
**For future questions**
1. The sum of the interior angles of a triangle is 180°
2. Alternate interior angles are congruent
3. The exterior angle of a triangle is the sum of the nonadjacent interior angles

Answer:
260
Step-by-step explanation:
76 rounded to 1 s.f. is 80
46 rounded to 1s.f. is 50
80+50+80+50= 260
Hope this helps!
Answer:
14 degrees
Step-by-step explanation:
