Answer:
1
Step-by-step explanation:
12+[2-(4 × a²)] ÷ 7+b
= 12+[2-(4 × 5²)] ÷ 7+ 1
= 12+[2-(4 × 25)] ÷ 7+ 1
= 12 + (2 - 100)÷ 7 + 1
= 12 - 98 ÷ 7 + 1
= 12 - 14 + 1
= 1

Answer:
x=43°
Step-by-step explanation:
The angles are adjacent and create a straight line so their sum is 180°.
(x+6)°+(3x+2)°=180°
x°+6°+3x°+2°=180°
4x°+8°=180°
4x°=172°
x=43°
