D. Customer who buy at least 25 tickets will pay $1.50 each
Law of sines says
a/sinA=b/sinB=c/SinC
where a,b,c are sides of a triangle and A,B,C are angles respectively.
a/sin45.1=c/sin59.1
(we can find angle C by sum of angles of a triangle is 180.)
a=sin(45.1) x 10.2/sin (59.1)
a=0.708 x 10.2/0.85
a=8.496
a=8.5 units
now u can find b and c sides.
Answer:
1.5 times
Step-by-step explanation:
450=30 minutes
450*2=900=60 minutes
150=15 minutes
150*4=600=60 minutes
900/600=1.5 times
