Answer: 117
Step-by-step explanation: Angle FAB is just 360 degrees minus all the other angles except 30. If you view the green/shaded area as a circle, there are 360 degrees, and FAB is a section of it. So 360-70-71-48-54=117. I hope this helps!
Answer:
8
Step-by-step explanation:
Y×2+3=19
19-3=16
16÷2=8
You subtract the 3 first to get what the number was when doubled. After getting that number you would divide it by 2 to get the number that you thought of.
<span> Train1 = 85 mph</span>
Train 2 = 105mph
85+105 = 190 mph combined speed
Time = distance/ speed
Time = 456/190 = 2.4 hours = 2 hours and 24 minutes

![[ \ where \ k \ is \ a \ constant \ ]](https://tex.z-dn.net/?f=%5B%20%5C%20where%20%5C%20k%20%5C%20is%20%5C%20a%20%5C%20constant%20%5C%20%5D)
<em><u>Find k.</u></em>
Given x = 12, y = 5,

b)
<em><u>Find x.</u></em>
Given y = 10
We have k = 300

c)
<u><em>Find y</em></u>
Given x = 3
We have k = 300
