Addison Guerrero · Answer 1

70° because the triangle must equal 180°. Therefore, 55+55=110. If the triangle must equal 180° then you subtract by the 2 angles that you have from 180°. That should get you to 180°-110° which equals 70°

Cinnamon · Answer 2

70°

Step-by-step explanation:

55 plus 55 = 110

180 - 110 = 70
