Answer:
2x+57°+x=180 ( angle sum property of triangle)
3x=123
x=41
I believe that the answer is speed in this situation but I'm not 100% sure
It's 42 because 2 times 42 is 84. Then 2 times 8 is 16 so take 84 - 16 is 68
Answer:54
Step-by-step explanation:
Pentagon has 5 sides
n=5
Sum of interior angles=180(n-2)
Sum of interior angles=180(5-2)
Sum of interior angles=180x3
Sum of interior angles=540
Size of each interior angle =540/n
Size of each interior angle =540/5
Size of each interior angle=108
x=108/2
x=54
The answer is 6.5
welcome!
