Question

find angle PON and angle NOP​

Answer 1

Answer:

angle PON = angle MOL. {vertically opposite

angles}

=> angle MOL = 180°- 90° { angle sum property}

=> angle MOL= 90°=angle PON****

***angle NOP= angle PON***

Step-by-step explanation:

Hope it helps...

Answer 2

Answer:

in triangle LOM the angles are given

angle LOM=180°- (70+20)

angle LOM = 180-90

LOM= 90

angle pon=lom (intersecting lines have opposite angles equal)

Step-by-step explanation:

PNO=70 given

PON=90 proved.

therefore, angle OPN = 180-(70+90)

OPN = 20° in the same way(angle sum property of a triangle)
