Question

What is the value of p?

Answer 1

35 would be the value of P so the answer would be C

Answer 2

We can first find the other two angles in the triangle. We are given that one external angle is 90 degrees. Then, its linear pair inside the triangle is 180 - 90 = 90 degrees.

Similarly, the other external angle is 125 degrees. Its supplement inside the triangle is 180 - 125 = 55 degrees.

The total degrees of a triangle should be 180. We have two of the three angles: 55 + 90 = 145 degrees.

To find p which is the third angle, we just do 180 - 145 = 35 degrees.

So, the answer is (C).
