Question

in quadrilateral Plan , angle p: angle l 70 and angle a =100 ,then find angle n​

Answer 1

Answer:

120

Step-by-step explanation:

angle sum of a quadrilateral=360

360=70+70+100+n

360=240+n

n=360-240=120

Answer 2

$\angle N=120^{\circ}$

Step-by-step explanation:

In quadrilateral PLAN

Angle P=angle L=70 degree

Angle A=100 degree

Sum of angles of quadrilateral=360 degrees

Therefore,

$\angle P+\angle L+\angle A+\angle N=360$

Substitute the values

$70+70+100+\angle N=360$

$240+\angle N=360$

$\angle N=360-240$

$\angle N=120^{\circ}$
