Answer:
Initially:
Cam has X stickers.
Dan has 2x.
Dan gives Cam 15 stickers:
Cam has x + 15 stickers.
Dan has 2x - 15 stickers.
2x - 15 = (x + 15) + 22.
X = 52 stickers.
x + 15 = 52 + 15 = 67 stickers.
2x - 15 = 2*52 - 15 = 89 stickers.
Step-by-step explanation:
Cosine is positive in Quadrant IV.
1. 180-146=34°
2. 40° (alternate angles are equal)
3. 50° (vertically opposite angles are equal)
4. 180-75=105° (co-interior angles add up to 180°)
5. 90-65=25°
Hope my answer helped u :)
Manual is correct due to 5^2 and 7^2 being 74 in total while 5+7 is 12 being squared gives you 144 which is the correct answer.
