Answer:
The m∠ U is 72°.
Step-by-step explanation:
Given:

To find :

Solution:
The sum of the measures of the interior angles of a polygon with 'n' sides is given as

Here we have n = 5 on substituting the values we get

Therefore,
m∠ U is 72°.
The first choice can be any one of the 8 side dishes.
For each of these . . .
The 2nd choice can be any one of the remaining 7.
Total number of ways to pick 2 out of 8 = (8 x 7) = 56 ways .
BUT ...
That doesn't mean you can get 56 different sets of 2 side dishes.
For each different pair, there are 2 ways to choose them . . .
(first A then B), and (first B then A). Either way, you wind up with (A and B).
So yes, there are 56 different 'WAYS' to choose 2 out of 8.
But there are only 28 different possible results, and 2 'ways'
to get each result.
Step-by-step explanation:
This time round, use SOH method (Sin angle = Opposite/Hypotenuse)
given Opposite = 7
Hypotenuse = 10

Answer:
0.5 I think. because for every 2 on the x axis, it grows 1 on the y axis.
When changing fractions into decimals the whole number goes before the period and the fraction goes after.The denominator of the fraction will tell you whether or not you need to put any zeros before the numerator. If the denominator is 10 zeros are not needed.The end result is 7.2 and can be read as seven tenths.
