Question

5.find the value of x.
6. find the value of y

Answer 1

Using the rule of supplementary angles;

180=y+135
180-135=y
45=y

You also know that the internal angles of a triangle always adds up to 180;

180=90+45+x
180=135+x
180-135=x
45=x

Therefore, the values of x and y are 45 degrees each.

Hope I helped :)
