Answer:

I hope that this is the right answer...

Answer 2

We've triangle ABC

BY ANGLE SUM PROPERTY

$= > < a + < b + < c = 180$

$= > 90 + 30 + c = 180 \\ = > 120 + c = 180 \\ = > c = 180 - 120 \\ = > 60$

But now we need to find x angle

since we know angle forming on straight line equals to 180

Therefor

COB is straight line

=90+x=180(linear pair)

x=180-90

x=90
