two sum two 180

Adjacent angles that form a straight angle

(2x+24) + (4x+36) = 180 6x + 60 = 180 6x = 120 x = 20 2(20) + 24 = 4(20) + 36 = 64° 116°

ray that divides an angle into two congruent angles (2x – 7) B C A D (2x – 7) + (2x – 7) = 3x – 3 2(11) – 7 = 3(11) – 3 = 15° 30° (2x – 7) (2x – 7) x=11

Take five minutes and look over the terms you learned last week independently. Put all your notes away. For each slide, ALL teams will answer the question on your whiteboards. Wait to reveal your answer. For each problem, pass the whiteboard so everyone in your team takes a turn as the scribe/spokesperson.
