Question

Q10) In the given figure find x​

Answer 1

Answer:

x=30°

Step-by-step explanation:

from triangle ABC ,

sum of the interior angles =180°

40°+90°+y=180°

y=50°

from triangle BDE,

x°+100°+50°=180°

x=30°

Answer 2

Answer:

x= 30°

Step-by-step explanation:

in triangle abc 90°+40°=130°

180°-130°=50°

take the left out angel as y

so y=50°

in triangle bde

100+y

100°+50°=150°

180°-150°=30°

thus, x=30°

in a triangle all interior angels should add upto 180 so we took 180 in the above problem
