Respuesta :
The measure of the fourth interior angle in the quadrilateral is 145
sum of quadrilateral is 360
so 360 - (65 + 75 + 121)
=360 - 261
= 99
answer: 99 is the measure of the fourth interior angle in the quadrilateral
so 360 - (65 + 75 + 121)
=360 - 261
= 99
answer: 99 is the measure of the fourth interior angle in the quadrilateral
