If a and b are in different triangles then the true option is that values of a and b can't be determined.
What is triangle?
A triangle is a two dimensional figure having three sides and three angles.
Sum of angles of a triangle is equal to 180° whether it is a right angled or not.
How to find angle?
In first triangle one angle is x°, second is 75° and third one is a° and in second triangle one angle is 60°, second is y°, third one is b°.
Sum of angles in first triangle is x+75+a=180
Sum of angles in second triangle is y+60+b=180
because any relationship between x and y is not given in the questions so values of a and b cannot be determined.
Hence the correct option is D which is that values of a and b cannot be determined.
