Answer:
up and down
Step-by-step explanation:
Im pretty sure its up to down
y = 0
The midline is y = 0, because the greatest value (crest) is at y = 1, and the lowest value is y = -1, which, when you average it out, is 0. This makes the midline y = 0
1. 0.004, 4%, 4 x 10^-1, 1/4, 4/9
2. 6%, 16%, 1/6, 0.6, 6x 10¹
3. 7%, 7.5 x 10^-2, 3/4, 7/10, 7.5
4. 2%, 3/16, 1/5, 2/9, 2 x 10²
m∠1 = 108°
m∠2 = 72°
By applying triangle sum theorem in the given triangle,
Sum of all interior angles = 180°
38° + 70° + m∠2 = 180°
m∠2 = 180° - 108°
= 72°
Since, angles 1 and 2 are the linear angles,
Therefore, m∠1 + m∠2 = 180°
m∠1 + 72° = 180°
m∠1 = 180° - 72°
x = 13
8x + 16 = 120
8x = 104
