Question

In the adjoining figures show that triangle ABC congruent to triangle DBC and the find the
values of x and y

Help please.....​

Answer 1

Answer:

in this triangle side ABC is parallel to side DBC the sides given agar upper waala 40 degree hai toh niche waala bhi 40 degree hooga because their side are equal to 90degree

Step-by-step explanation:

phle aapko (2y+6)degree ko niche directly bracket open krke 2y+6=56

2y= 56-6 = 2y=50

y=2/50 = 25 Ans

Answer 2

Answer:

x= 84°

x= 84°y= 25°

Step-by-step explanation:

In triangle ABC and DBC

2y+6 = 56(angles between 2 equal sides are equal)

2y = 56-6

2y = 50

y = 50/2

y = 25

AND

In triangle DBC

angle d OR x = 180-( b+ c)

angle d/x = 180-(56°+40°)

angle d/x= 180-96°

angle d/x = 84°
