Question

if the angle of a quadrilateral are x°,(2x+13)°,(3x+10)°,(x-6)° find the value of x​

Answer 1

Answer:

x

∘

,(x+10)

∘

,(x+20)

∘

,(x+30)

∘

Sum of all the angles of a quadrilateral =360

∘

∴x

∘

+(x+10)

∘

+(x+20)

∘

+(x+30)

∘

=360

∘

⇒4x+60

∘

=360

∘

⇒4x=300

∘

⇒x=

4

300

=75

∘

∴ each angle is as follows

x

∘

=75

∘

,(x+10)

∘

=85

∘

,(x+20)

∘

=95

∘

,(x+30)

∘

=105

if correct mark me as brilliant

Answer 2

Answer:

value of x is 49

Step-by-step explanation:

x+2x+13+3x+10+x-6=360

7x+17=360

7x=360-17

7x=343

x=49

please mark me brainliest

hope it helps !!!
