Answer 1

Answer:

20

Step-by-step explanation:

All angles of a triangle equal 180. To find what angle BCA equals, we need to solve:

30 + 80 + BCA = 180

110 + BCA = 180

BCA = 70

Since angle BCA and x form a right angle, we know that when we add them together, we will get 90. So:

70 + x = 90

x = 20
