Answer:
60 degrees
Step-by-step explanation:
Since the angle 120° is in the second quadrant, the reference angle formula is Ar=180°−Ac A r = 180 ° - A c . The reference angle is Ar=60° A r = 60 ° .
Answer:
x = 25
y = 21
Step-by-step explanation:
4x + 10 + 3x - 5 = 180° because these two angles makes a straight line
7x + 5 = 180° subtract 5 from both sides
7x = 175° divide by 7
x = 25
2y + 28 + 4y + 26 = 180° because the sum of these angles is equal to a straight line's measure
6y + 54 = 180° subtract 54 from both sides
6y = 126 divide both sides by 6
y = 21

Step-by-step explanation:
Very interesting problem. Be thankful it is not a six sided dice.
Part A
1 1
1 2
1 3
1 4
2 1
2 2
2 3
2 4
3 1
3 2
3 3

4 1
4 2
4 3
4 4
Part B
There are 16 possible out comes
1 4
4 1
2 3
3 2
4 out of the 16 outcomes are possible
P(5) = 4/16 = 0.25
Part C
The theoretical out come would be 4 times
4/16 = 0.25
On a hundred rolls, you would expect to get 25 sets of doubles.
Information given to us:
10 4/5 total cake batter
18 cupcakes
First, we need to find the improper fraction of 10 4/5, which is 54/5. Now we can divide 54/5 by 18. Answer: every cupcake will use 3/5 cup.
