Answer:10
Step-by-step explanation:
A. angel a is 50 bc since it is isosceles, the two ungiven angles equal the same (180-80=100, 100/2=50)
B. 180=28+28+b, 180=56+b, 124=b

ran 4/5 miles. We need to find the tenths that is present to the given number
which is 4/5.
4/5 is a fraction, and since we are looking for tenths which is a decimal
value. Thus, we need to convert this fraction to decimals.
To convert, simply divide the numerator by the denominator.
In the given number, 4 is our numerator and 5 is our denominator.
=> 4 / 5
=> 0.8
Therefore, 8 is the value of tenths because it is the number next to the
decimal point.

The question is asking how many combinations of two people can be made from a group of ten people.
Using the formula C(10,2) = 10!/(2! x (10 - 2)! = 10!/(2! x 8!) = 45 handshakes.
A simple way to prove this is each person shakes the hand of 9 other people
10 x 9 = 90 but this counts every handshake from the view of both people involved.
The actual number of handshakes is therefore 90 / 2 = 45
