Answer:
y = 55 degrees.
Step-by-step explanation:
the angles of a triangle add up to 180 degrees, so
40 + y + y + 30 = 180
2y = 180 - 70
2y = 110
y = 55.
Answer:
answer is 17.5
Step-by-step explanation:
use formula a^2 + b^2 = c^2 (letters represent each side of the triangle)
9^2 + 15^2 = 306
306 = x^2. find the square root of 306 to find x
√306 = 17.4928557
rounded it to the nearest 10th
17.5

To find the mean absolute deviation of the data, start by finding the mean of the data set.
Find the sum of the data values, and divide the sum by the number of data values.
Find the absolute value of the difference between each data value and the mean: |data value – mean|.
Find the sum of the absolute values of the differences.
Divide the sum of the absolute values of the differences by the number of data values.
