Question

one angle of a quadrilateral is 108° and the remaining three angles are equal. find the three equal angle​

Answer 1

Answer:

a+b+c+d=360

108+3x=360

3x=360-108

3x=252

x=252\3

x=84

Answer 2

Answer:

let the angle of quadrilateral be

a,b,c,d

so

a= 108

let b=c=d=x

thus

a+b+c+d=360

108+x+x+x=360

108+3x=360

3x=360-108

3x= 252

x=252/3=84
