A.
because the total distance of every triangle 180. Add the two other angles so 42+ 57 =99. Then you have to subtract those two combined angles to find the missing one from the total distance, which is 180. 180-99=81. the answer is A. 81
Answer:7 4ts
Step-by-step explanation:
Three colors * 8 possible sizes = 24 different shoes
The probability that the shoe is going to be a size 9 black shoe is 1/24.
2x-7=29
"Seven less than" => minus 7.
"Two times <u>a number</u>" => 2x (x is the unknown number)
"is twenty-nine" => =29
Putting it all together,
-7 + 2x = 29
or
2x-7=29
(if you were wondering x is equal to 18)
D is your answer
1/3 of 18 is 6, so 2/3 would be 12
