Question

WHAT IS THE ANSWER
IS IT:
30
35
40 OR
45?

Answer 1

Answer:

Here we can see that 130° and a angle form linear pair so let's find it

Let It be z°

130° + z° = 180°

z = 180 - 130

z = 50°

Now, We can see that z° + x° + 90° = 180°

50 + 90 + x = 180

x = 180 - 140

x = 40°

So answer is 40°
