please answer my question now please answer now ​

Answer 1

Step-by-step explanation:

$x + 2x + 4x + 5x = 360$

$12x = 360$

$x = \frac{360}{12}$

$x = 30$

$2(30) = 60$

$4(30) = 120$

$5(30) = 150$

Answer 2

Answer:

Step-by-step explanation:

7.

• X+2X+3X+4X= 360° (Sum of the angles of a quadrilateral)
• 10x=360°
• x= 360° / 10
• x= 36
• Angle 1 = x = 36°
• Angle 2 = 2x = 2*36 = 72
• Angle 3 = 3x = 3*36 = 108
• Angle 4 = 4x = 4*36 = 144

8.

• x + (x-5)° + (x-5)° + (2x-5)°  + (2x-5)°  + (2x+20)°  =  360° (Sum of the angles of a quadrilateral)

• 9x° +20° -20° =360°
• 9x°=360°
• x° =360°/9

1. x°=40°
2. x-5 = x-5 = 40°-5° = 35°
3. 2x-5 = 2x-5 =2(40) -5 =80°- 5° = 75°
4. 2x+20° = 80+20 =100°
