Question

What do you know to be true about the values of A and B

Answer 1

I think it’s can’t be determined because we need to know at least 2 angles of a train for.

Answer 2

Answer with explanation:

There are two triangles.We will use angle sum property to get the correct Inequality.

In Triangle 1

→x° + a° + 75°=180°

→x° + a°= -75°+180°

→x° + a°= 105°

In triangle 2

→y° + b° + 60°=180°

→y°+b°=180°-60°

→y°+b°=120°

As there are four different variables ,and only two equations.So,we can't determine the value of , a and ,b.

Option D: Can't be Determined
