Question

The bisector of Angle B and angle C of a quadrilateral ABCD meet at a point r are inside the quadrilateral if angle A = 95 degree and Angle D =111 degree find angle BRC

Answer 1

Answer:

154

Step-by-step explanation:

Given :

ABCD is quadrilateral.

Angle A = 95

Angle D = 111

To find :

Angle BRC

START :

angle A + angle D + BRC  = 360

111 + 95 + BRC = 360

206 + BRC = 360

BRC = 360 - 206

Therefore, BRC = 154

Answer 2

answer:-

£a+£b+£c+£d=360°

95°+£b+£c+111°=360°

£b+£c=360°-206°

£b+£c=154°

now, ∆brc

£b+£c+£r=180°

£r+1/2(£b+£c)=180°

£r=180°-77°

£r=103°
