Answer:

x = 10

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

5 + 3x + 70 + 75 = 180

3x + 150 = 180 ( subtract 150 from both sides )

3x = 30 ( divide both sides by 3 )

x = 10

The sum of all angles in a triangle is equal to 180.

75 + 70 + 5 + 3x = 180

150 + 3x = 180

3x = 180 - 150

3x = 30

x = 10

Third angle:

5 + 3(10)

Margaret [11]

So at the beginning, the friends eat 3 meat pies in total. So that leaves two meat pies left.
So basically, we divide the meat pies by the number of friends.
2/6 is 1/3
So each friend needs to eat 1/3 of a meat pie
