Question

If angles of quadrilateral 5x, 4x, 3x, 6x. What is the value of x.

Answer 1

Answer:

∴ x = 20°

Step-by-step explanation:

solution,

  5x + 4x + 3x +6x = 360° [∵ sum of angles of quadrilateral]

or, 18 x = 360°

or, x = 360°/18

∴ x = 20°

Answer 2

Step-by-step explanation:

5x+4x+3x+6x=360

5x+4x+3x+6x=36018x=360

5x+4x+3x+6x=36018x=360x=360/18

5x+4x+3x+6x=36018x=360x=360/18x=20

5x+4x+3x+6x=36018x=360x=360/18x=205x=5×20=100

5x+4x+3x+6x=36018x=360x=360/18x=205x=5×20=1004x=4×20=80

5x+4x+3x+6x=36018x=360x=360/18x=205x=5×20=1004x=4×20=803x=3×20=60

5x+4x+3x+6x=36018x=360x=360/18x=205x=5×20=1004x=4×20=803x=3×20=606x=6×20=120
