In the figure, the right angled triangle denotes the 3 sides as 90°, 50°and (30+x)°. Clearly, we know the sum of the 3 sides of any triangle should be 180°. So adding, we get 170°+x°. Hence, equating we get x= 10°.

A is the answer.

CBA = 180 - 120 = 60
CBD = 180 - 60 = 120

Now in triangle CBD ,
x + 50 + 120 = 180
x = 10

IMO A

Solution:

Its a question to observe and make simple inference based on Properties of Triangles.

Angle CBA = 180-(90+30)=60 degrees

=>This is an external angle to the internal opposites x and 50 degrees=> x+50=60

=>x =10 degrees (option a)
