Question

Sum of all the angles at a point is 360°

∴ 1x + 4x + 7x = 360°

___ = 360°

x =______



The angles are 1x = 1 × ___ = ____

4x = 4 × ___ = ____

7x = 7 × ___ = ____

3. The angles at a point are x° , 2x°, 3x°, 4x° and 5x°. Find the value of the largest angle.​

Answer 1

Answer:

12x= 360°

x=360/12

x= 30

1x=1×30=30

4x=4×30=120

7x=7×30=210
