Given :
- The angles of a triangle are
- The difference between the two angles x and y is
To Find :
- The values of
Solution :
Now let the 2 unknown angles be,
- X
- X + 30
☆ As it's mentioned that their is 30
here,
- As per the angle sum property we know that sum of interior angles in a triangle is
Now let's apply this property and find the angles
hence the angles are,
● So, option C is correct
Verification :
- Let's check weather their sum equals 180° to know weather we went right
Left hand side equals Right hand side

- The sum of the length of any two sides of a triangle is greater than the length of the third side.
- The side opposite to the largest angle of a triangle is the largest side.
- Any exterior angle of the triangle is equal to the sum of its interior opposite angles
- The sum of consecutive interior and exterior angle is supplementary.
- The exterior angles of a triangle always add up to 360 degrees
hope this helps ☆
