Answer:
x=17
Step-by-step explanation:
(5x-58)=(2x-7)  ->(because of cosine-rule)
3x=51
x=17

Ok first you have to convert 100 miles to feet.
A mile is 5,280 feet
100x5,280
528,000
Thats how much feet per hour. Now we need to find feet per second. So lets divide 528,000 by 60 
528,000/60
8,800
Now we know 8,800 is how much feet per minute now we divide it once more by 60 to find feet per second.
8,800/60
146 2/3
So your answer is 146 2/3ft/sec

Answer: R = (4, 5)
Step-by-step explanation: Midpoint is simply the center of a line. So, the equation for it is ((x1+x2)/2, (y1+y2)/2). Hence for this,
x coordinate- (6+x)/2=5
                         x=4
y coordinates- (9+y)/2=7
                          y=5
And therefore R is (4, 5)
