Answer:
B seems right
Step-by-step explanation:
Answer:
x = 27
Step-by-step explanation:
mean is calculated as
mean = 
sum = 2 + 7 + x = 9 + x and count = 3 , then
= 12 ( multiply both sides by 3 to clear the fraction )
9 + x = 36 ( subtract 9 from both sides )
x = 27
Answer:
69°
Step-by-step explanation:
if CA and AT are congruentsides, this means that the angle of C and T must also be the same.
In order for a triangle to be a triangle, they must meet the angle of 180 degrees.
We know CAT is = to 42
So we subtract 42 from 180 = 138 degrees
we then divide 138 by 2 and we get 69
angles c + t are both 69 degrees
Basically you have to round the numbers to find and get your answer
