Answer:
92∘
Step-by-step explanation:
Supplementary angles combine to create a straight angle. So, they have a sum of 180.
∠x + ∠y
∠x + 88 --------------> 180
=92∘
This is a parallelogram, and the answer is 8.04
SQRT each individual bit: 4 and
and 9 and
1.924 and 5.77
step 1: find the mean by adding up all the numbers and divide the sum by the number of numbers.
step 2: find the difference between each number and the mean, square the difference
step 3: add up all the results of step 2, divide the sum by (n-1), n is the number of numbers.
step 4: square root the result of step 3.
it is a long process.
