Question

the measure of one angel of a quadrilateral is 150 and other three angels are equal in measure. find the measure of each of the equal angel​

Answer 1

Answer:

let ABCD be the given quadrilateral.

then

angle A =150

let other three angles be x

according to the question,

A+3x=360

150+3x=360

3x=360-150

3x=210

x=210\3

x=70

now the other angles are of 70 degree each.

Answer 2

Answer:

70,70 and 70

Step-by-step explanation:

sum of the angles of a quadrilateral is 360

=150 + 3x =360

=3x=360-150=210

=x=210/3=70
