Answer:
x = 16
Step-by-step explanation:
the labeled angles are all exterior
the sum of all exterior angles always equals 360 degrees
9x+1 + 5x+12 + 10x-37 = 360
24x - 24 = 360
24x = 384
x = 16
It would be Y=80

Answer:
3.5 km
Step-by-step explanation:
For this question, we must use the pythagorean theorem: +=
C is the hypotenuse which is 4 km. We can set A as 2 km. We would plug in the values to get + =.
Then we must isolate the b value. We get = -. This then simplifies down to =12. Then we square root both sides to get b=3.5
