Answer:
Step-by-step explanation:
apply sine rule 2 the triangle on left:
sinB'/10=sin45deg/8.2
sinB'=10*sin45deg/8.2=0.8623
B'=59.58deg or 120.42deg
as shown in the pic, B' > 90deg.
so B'=120.42deg.
the triangle on right has 2 sides at 8.2 so it is isosceles
B=adjacent < of B'
=180-120.42
=59.58deg

Answer:
45 premium tickets were sold
Step-by-step explanation:
p = premium
d = deluxe
r = regular
p+d+r = 273
6p+4d + 2r = 836
118+d = r
Replace r with 118+d
p+d+118+d = 273
p +2d = 273-118
p+2d = 155
6p+4d + 2(118+d) = 836
6p+4d + 236+2d = 836
6p +6d = 836-236
6p + 6d = 600
Divide by 6
p+d = 100
d = 100-p
Replace d in p +2d= 155
p +2(100-p) = 155
p+200-2p = 155
-p = 155-200
-p =-45
p =45
