Answer:
Step-by-step explanation:
If we have 3 red spaces, 5 white spaces, and one blank space, there are a total of 9 spaces.
Since there are 3 red spaces, there is a 
chance of getting a red. However, the question asks the probability of not getting a red, so the chances of not getting a red are 
.
Hope this helped!

Áp dụng tính chất của đường trung bình ta có:
20+x=2.(2x+22)
20+x=4x+44
X-4.x=44-20
-3.x=24
X=24/-3x=-8
Trong độ dài ko có độ âm nên tất cả đại lượng hình học đều mang dấu (+) vì vậy kết quả cuối cùng sẽ là 8

Answer:
7.2
Step-by-step explanation:
Apply Law of Cosines, given that b is 13.5, c is 8.9, and Angle a is 29.
I think it could be b cause it does have sum solution or it could be A at the same time so try to used the calculator and if it comes up with less then then it could be A if it comes up with more then, then it could be B
Supplementary means they equal 180 when added. Therefore:
X+56+3x=180
Combine common units
4x+56=180
Subtract 56 from both sides
4x=124
Divide by 4
X=31
Now we know the smaller angle is 31 degrees. Now we plug that into the larger angle:
3(31)+56
93+56
149
The larger angle is 149 degrees.
I hope this Helps!
