Question

one angle of an quadrilateral is 111 degrees and the remaining three angles are equal find the measure​

Answer 1

Answer:

total angle of any quadrilateral : 360

Measure of given angle = 111

Let each of the remaining three agles measure ‘x’

So that, 360 = 111 + 3x

or 360 - 111 = 3x

or 249 = 3x

or x = 249/3 = 83

Ans. Each of the other three angles measure 83 degrees.

Answer 2

Answer:

let the other three angles be x.

Step-by-step explanation:

111+x+x+x=360 DEGREE (ASP of quadrilateral)

111+3x=360

3x=360-111

=249

x=249/3

=83 DEGREE.

therefore the other three angles are 83 degrees.

check::

83+83+83+111=360.

hope it helps!
