Answer 1

Answer:

75

Step-by-step explanation:

As it is a trapezium, its 1 pair of sides is parallel.

Now, we know that the sum of the interior angle of the same side of parallel lines should be 180°.

So, it's clear that angle A =180 - 100 = 80.

Similarly, angle B=180 - 50 =130.

2x = A

or,2x = 80

or,x = 40

And,2y = B

or,2y = 130

or,y = 65

The sum of the interior angles of a triangle is 180°.So,angle P = 180 - (40+65) = 75
