Given the heights of the 6 tomato plants sample below:
55.6, 59.4, 59.9, 62.9, 64.9, 69.2
Point Estimate,

Please include the following items
Step-by-step explanation:
By Exterior Angle Theorem,
(x + 40)° + (4x - 5)° = (6x + 20)°
Therefore 5x + 35 = 6x + 20 and x = 15.
Hence angle QPT = (6 * 15 + 20)° = 110°.
Square root 10 times 36 root n
