Answer 2

angle a = 20 + angle b

angle a = 20 + angle bangle a + angle b = 180

angle a = 20 + angle bangle a + angle b = 18010 + angle b = 90

angle a = 20 + angle bangle a + angle b = 18010 + angle b = 90 angle b = 80

angle a = 20 + angle bangle a + angle b = 18010 + angle b = 90 angle b = 80angle a = 100.

angle a = 20 + angle bangle a + angle b = 18010 + angle b = 90 angle b = 80angle a = 100.plz mark as branlist.
