Answer:
Step-by-step explanation:If you choose any 3 of the 7 vertices, you can connect them with lines to create a unique triangle.
So, the question becomes "In how many different ways can we select 3 vertices from 7 vertices?"
Since the order in which we select the 3 vertices does not matter, we can use COMBINATIONS.
We can select 3 vertices from 7 vertices in 7C3 ways.

Answer:
Total cookies (including all types) made by Hilary = 48 + Y
Step-by-step explanation:
Total chocolate chip cookies made by Hillary = 48
Total sugar cookies made by Hillary = Y
Total cookies (including all types) made by Hilary = Total chocolate chip cookies + Total sugar cookies
Substituting the given values, we get -
Total cookies (including all types) made by Hilary = 48 + Y
Answer:
B = 38°
Step-by-step explanation:
A straight angle is 180°. If your four angles total a straight angle, then ...
60 +2x +3x +25 = 180
95 = 5x . . . . . . subtract 85
x = 19 . . . . . . divide by 5
2x = 38 . . . . . angle B is 38°
