Question

13 no. plz help fast . tomorrow is my exam

Answer 1

Hi mate!!

Q.1

Angle (NOM) + Angle (OMP) + Angle (MPN) + Angle (PNO)=360. because sum of angles of a four sideded fig is always = 360.



Angle (NOM) =35°. ,. Angle (OMP)= 90°. ,. Angle ( MPN)=? and Angle (PNO)= 90°


So,

Angle (MPN) = 360° - 215°

Angle (MPN)= 145°



!!!!!!!! Hope it helps!!!!!

Answer 2

angle NPM+ANGLE PMO+ANGLE MON+ANGLE NPM= 360° (ANGLE SUM PROPERTY OF QUADRILATERAL)
90+90+35+NPM=360
215+NPM=360
NPM=360-215
NPM=145
