Question

In quadrilateral plan angle P is equals to angle l is equals to 70 degree and Angle A is equals to 100 degree then find angle N

Answer 1

Answer:

10

Step-by-step explanation:

100+70=170

180-170=10

Answer 2

In quadrilateral PLAN angle $\mathbf{\angle N=120^{\circ}}$

Step-by-step explanation:

1. Given data in quadrilateral PLAN

  $\mathbf{\angle P=70^{\circ}}$

  $\mathbf{\angle L=70^{\circ}}$

  $\mathbf{\angle A=100^{\circ}}$

2. In any type of quadrilateral sum of all interior angle is 360°

3. So we can say that

   $\mathbf{\angle P+\angle L+\angle A+\angle N=360^{\circ}}$

  On putting respective value, we get

  $\mathbf{70+70+100+\angle N=360^{\circ}}$

  $\mathbf{240+\angle N=360^{\circ}}$

  $\mathbf{\angle N=360-240}$

  So

  $\mathbf{\angle N=120^{\circ}}$

  Value of angle N is 120°
