Answer:

Given :

→x-y=12

→xy= 3²

=9

Equation formed:

{(x - y)}^{2}  =  {x}^{2}  +  {y}^{2}  - 2xy

Step by step explanation:

{(12)}^{2}  =  {x}^{2}  +  {y}^{2}  - 2 \times 9 \\  144   + 18 =  {x}^{2}  +  {y}^{2}  \\  = 162

hope it helped you:)

melisa1 [442]

answer:

y = 114°    and   x = 120°

step-by-step explanation:

part A:

  • one inner angle: 51°
  • second inner angle: (180°-87°) = 93°
  • third inner angle: (180°-30°) = 150°
  • fourth, beside y angle: 360° - 150° - 93° - 51° = 66°
  • then y = 180°  - 66°  = 114°

part B:

  • there are 6 sides, so inner angle: (6-2)*180 = 720°
  • 160° + 123° + 107° + 90° + x + x = 720°
  • 2x + 480° = 720°
  • 2x = 720° = 480°
  • 2x = 240°
  • x = 120°

2(3+3) or 2(3)+6, so the answer is the third option. It’s just using the distributive property.
