|a+b| + |c| when a= -5, b= 8, c= -13:
|-5+ 8|+ |-13|
= |3|+ 13
= 3+ 13
= 16
The correct answer is D. 16~
we have: ∠P + ∠Q + ∠R = 180°
<=> (4x – 14)º + (5x + 6)° + (x - 2)° = 180°
<=> 4x – 14 + 5x + 6 + x - 2 = 180°
<=> 10x - 10 = 180°
<=> 10x = 190
<=> x = 19°
So: ∠R = (x - 2)° = (19 - 2)° = 17°
ok done. Thank to me :>
