Hmm, find the missing angles

all angles inside triangle add to 180
ABC
130+x+15=180
145+x=180
x=35

DEF
35+15+y=180
50+y=180
y=130


ABC has 130, 35, 15
DEF has 35, 15, 130
I would say they are similar because of the first option

ST is a midsegment, which tells you that BD=2(ST) or ST=½BD. Use that to substitute the values and find ST.
BD=2(ST)
29+x=2(2x+31)
29+x=4x+62
29=3x+62
-33=3x
x=-11
Now that we know x, we can substitute that into 2x+31 to find ST
ST=2x+31
ST=2(-11)+31
ST=-22+31
ST=9

Can someone please explain to me please
sveta [45]

Answer:

  120

Step-by-step explanation:

nCk or C(n, k) are ways to write the "combinations" function. That function tells you how many combinations of n things there are when they are taken k at a time.

Here, you have 10 vegetables, and you want to count the number of ways you can take 3 at a time. You are being asked to find the value of 10C3, or C(10,3). You do this by putting 10 where n is in the formula, and 3 where k is. Then do the arithmetic.

  10C3 = (10!)/(3!(10-3)!) = 10·9·8/(3·2·1) = 5·3·8 = 120

120 3-vegetable plates may be made.
