Question

2. In the adjoining figure, angle b= 70° and angle a = 50°. if bisector of angle c meets ab in d then find angle adc​

Answer 1

Step-by-step explanation:

according to triangle sum property the sum of all angles of a triangle is equals to 180 degree

so angle c will be of 60 degree

and in triangle ADC angle d will be of 100 degree

Answer 2

we know that. for any triangle

angle A + angle B + angle C =180⁰

=> 50⁰+70⁰ + angle C =180⁰

=> angle C = 60⁰

In the given figure AC is a bisector of angle C ,

so angle DCB = 30⁰

So,

angle ADC= angle B + angle DCB

= 70⁰+30⁰

= 100⁰
