Hello!
To find cosine, use the formula cos = adjacent / hypotenuse.
According to angle B, adjacent of angle B is side A, and the hypotenuse is side c because the hypotenuse is always opposite the right angle.
Therefore, the cosine of angle B is a/c.
Two lines that intersect at 90 degrees are considered perpendicular to each other.

8x would represent multiplying 8(people) times x(ticket cost) But you don't know how much the tickets cost per person so that's why it's x.
8x + 20 = 76
76-20=56
56÷8=7
x equals 7
