Question

If two angles of a quadrilateral measure 67°, 123°, and 58°, what is the measure of the other angle​

Answer 1

Answer:

angle D=112 degrees

Step-by-step explanation:

let the quadrilateral Be ABCD. angle A=67. angle B=123. angle C=58

Sum of all angles of quadrilateral = 360

angle (A+B+C+D)=360

67+123+58+angleD=360

248+ angle D=360

angle D=360-248

angle D=112
