Answer: 52 1/2 inches. Draw a vertical line up from the 20 week marker and where that line intersects the slanted red line and. Then take a straight edge and draw a line parallel to the "week" line on the bottom of the graph from the intersection to intersect the height line. Where the second line crosses the height line that number is the height of the plant at 20 weeks.
The correct answer is 58/7 (decimal: 8,28....)
Answer:
45°
Step-by-step explanation:
three angles in a triangle sum up to 180
90° + a + a = 180°
90° + 2a = 180°
2a = 180°-90°
2a = 90°
a = 45°
