What Is The Answer class=

Sagot :

To find :

  • angle of 3x

Hint :

  • first we have to find the value of x

Step by step expansion:

  • x + 2x + 3x + 4x + 5x = 180°

Why?

Reason: angles that are formed on a straight line is equal to 180°

  • 15x = 180°

  • x = 180°/15

  • x = 12

.°. value of x = 12

we need value of 3x

put the value of x in 3x

  • 3 × 12
  • 36°

REQUIRED ANSWER = 36°

Answer:

[tex]5x + 4x + 3x + 2x + x = 180° \\ 15x = 180° \\ x = 180° \div 15 \\ x = 12° \\ 3x = 12 \times 3 \\ 3x = 36°[/tex]
