A: 11% x 67530 = $7428.30
B: 8% x 85740 = $6859.20
Person A made more commission
Answer:
7.5
Step-by-step explanation:
I divided 30 by 4 and got 7.5
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°
