Question

What do you know to be true about the values of a and b

Answer 1

Answer: D . Cannot determined

Explanation:

In the given picture , we have two triangles .

In first triangle , we have three angles given as : 60° , a° and x °.

Here , measure of two angles is not given.

In second triangle , , we have three angles given as : 40° , b° and y °.

Here , measure of two angles is not given.

Also, the information that can link these two triangle is not given.

So , we cannot say anything about the measure of angles a and b.

Hence, he correct answer would be : D . Cannot determined

Answer 2

d) cannot be determined.

Explanation:

x + 60 + a = 180

40 + b + y = 180

Here we cannot find the missing angles because we should know angles to find a missing angle.

Therefore, answer d) cannot be determined.

Hope you will understand the concept.

Thank you.
