Question

31. In the given figure, ZA=80°,ZB=60°, ZC = 2.x° and ZBDC = y°. BD and CD bisect = angles Band C respectively. The value of x and y are respectively

​

Answer 1

Answer:

In tringle ABC (consider angle a and b as in fig)

Step-by-step explanation:

80°+a+a+b+b=180°[sum of angle of triangle ]

or,80+2a+2b=180° or,2(a+b)=100° or, 2(a+b)=100/2 or,(a+b)=50 nextt, or, a+b+x=180°[being sum of angle of triangle ] or,x+50=180° thus,x=130°=angleBDC thank u
