To find the value of angle h in the given decagon, we can use the fact that the sum of all the interior angles of a decagon is equal to (n - 2) * 180 degrees, where n is the number of sides of the polygon.
In this case, a decagon has 10 sides, so the sum of its interior angles is (10 - 2) * 180 = 8 * 180 = 1440 degrees.
To find angle h, we subtract the sum of the known angles from the total sum of the interior angles:
h = 1440 - (150 + 140 + 150 + 160 + 165 + 170 + 115 + 130 + 140)
h = 1440 - 1370
h = 70
Therefore, the value of angle h in the given decagon is 70 degrees.
