When a skateboarder starts from rest and moves down a hill with constant acceleration in a straight line for 6 seconds in a second trial he starts from rest and moves along the same straight line with the same acceleration for only 2 seconds. His displacement from his starting point compared with the first trial is one-ninth as large. This will make the answer choice C.

Look to the right of the number in the thousands
place. It's a 6, so round up.
8,636 is rounded to 9,000 because the highest place

Answer:
58°
Step-by-step explanation:
<h3>Angle sum property of triangle:</h3>
The sum of all angles of a triangle is 180°.
x + 69 + 55 + x + 78 = 180
x + x + 69 + 55 + 78 = 180
Combine like terms,
2x + 202 = 180
Subtract 202 from both sides,
2x = 180 - 202
2x = -22
Divide both sides by 2,
x = -22/2
x = -11
∠A = x + 69
= -11 + 69
