So what do you need us to do for you?
We know that
the law of cosines formulas established
c²=a²+b²-2*a*b*cos C-----> cos C=[a²+b²-c²]/[2*a*b]
a=11 m
b=12 m
c=16 m
so
cos C=[11²+12²-16²]/[2*11*12]---> cos C=0.0341
C=arc cos (0.0341)-------> C=88.05°
see the attached figure
the answer isthe angle is 88°
You must divide 62.5 by 5 to find the rate.
so...
it would be 12.5 dollars per ticket
Answer:
√17
Step-by-step explanation:
Distance Formula: d = SQR RT OF [(x-sub-1 minus x-sub-2)² + (y-sub-1 minus y-sub-2)²]
d = SQR RT OF [ (5-1)² + (3-4)² ] = SQR RT OF [ 16 + 1 ] = √17
d = √17
