Question

1. Two angles of a quadrilateral are 89° and 130. If the other two angles are equal, find the
equal angles. ​

Answer 1

Answer:

according to question :-

the remaining two angles are equal so let the two equal angles be x and x

now according to question :-

we know that sum of all angles of quadrilateral = 360 degree

so

89+130+x+x = 360

219+2x = 360

2x = 360-219

x = 141/2 = 70.5

hope you understand plz mark it as brainliest

Answer 2

Answer:

total angle of a quadrilateral=360°

let one angle be x

so,

89+130+x+x=360

219+2x=360

2x=360-219

2x=141

x=141/2

x=70.5°

so,one of the equal angle=70.5°
