Question

in the figure the bisectors of angle a to angle b meet at a point r if angle c =110°and angle d =50° find the measures of angle arb ​

Answer 1

Answer:

80°

Step-by-step explanation:

Supposing that ABCD is a quadrilateral.

A + B + C + D = 360 [angle sum property in

quadrilateral]

Let the measure of angle Abe = 2x

Let the measure of angle A be = 2y

.. 2x+2y+110+50 = 360

2x + 2y = 200

x + y = 100

In AARB sum of two angles is 100°

..ZARB = 180 - 100 = 80°
