Question

Ques-3 In figure ∆BAC=50° and ∆DBC-70° find the Value of x​

Answer 1

Answer:

Here ∠BDC=∠BAC=50

∘

since angles in same segment are equal

In △BCD, we have

∠BCD=180

∘

−(∠BDC+∠DBC)

=180

∘

−(50

∘

+60

∘

)

=180

∘

−110

∘

=70

∘

∴∠BCD=70

∘

Answer 2

Answer:

x= 60⁰

Step-by-step explanation:

a^+^b=180⁰(co interior angles )

50+x+70=180⁰

120⁰+X=180⁰

x=180-120

x=60⁰
