Question

the measure of four angles of a quadrilateral are 3x, 4x, 5x and 6x. find all the angles.
​

Answer 1

Step-by-step explanation:

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

18x=360

x=360/18

x=20

Where....

3x=3×20=60

4x=4×20=80

5x=5×20=100

6x=6×20=120

Hope this may help you

Answer 2

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

$18x = 360$

$x = \frac{360}{18} = 20$

$3x = 3 \times 20 = 60 \\ 4x = 4 \times 20 = 80 \\ 5x = 5 \times 20 = 100 \\ 6x = 6 \times 20 = 120$
