Question

find x
$answer \: should \: be \: 45$
I need answer fast ​

Answer 1

Answer:

4x+5°+x+5°+2x-10°+x°=360° (sum of exterior angles of a quadrilateral is 360°)

=>8x°=360°

=>x=360/8=45°

WE GET X=45°

X+5°=45+5=50°

4X+5=180+5=185°

2X-10°=90-10=80°

Answer 2

Answer:

we know that sum of all exterior angles of quadrilateral is 360°

so,

4x+5°+x°+2x-10°+x+5°= 360°

8x+10°-10°=360°

8x = 360°

x = 360/8

x = 45°
