Question

the angles of a quadrilateral are x, (x + 3 ), (x + 8), (x + 9) find the value of x

Answer 1

hi friend

here your answer looking for

in the given figure

angle A + Angle B + angle C + angle D = 360 degree
x+(x+3)+(x+8)+(x+9)=360
4x+20=360
x=85

angle A=x=85

angle B=x+3=85+3=88

angle C = x+8=85+8=93

angle D= x+9=85+9=94

hope it's helpful to you

so plz mark my answer as brainliest

Hi !

We know that ,
In a quadrilateral , the sum of the angles is 360°.

Hence,

x + x + 3 + x + 8 + x + 9 = 360
4x +  20 = 360
4x = 340
x = 340/4
   = 85

Value of x is 85
