hi <3

so basically, there are a few rules you need to know of and i'll describe those first.

angles in a triangle sum to 180 degrees. AND

angles on a straight line sum to 180 degrees

so, by using the first rule, we can calculate the missing angle within the triangle:

180 - (52 + 90) = 38

now, we can use the second rule to find x

180 - 38 = 142

x = 142 degrees

hope this helps :)
