Answer:
x=3
Step-by-step explanation:
Ok so basically, the number of student tickets is 3x, where x=the number of adult tickets sold. And we know that s(for student tickets)+x=480 total tickets sold. So if we replace s with 3x we have 3x+x=480, or 4x=480. We divide by 4 and get x=120, which is the amount of adult tickets sold.

Answer:
1 + tan 2θ = sec 2θ
Step-by-step explanation:
cos 2θ + sin 2θ = 1
Dividing by cos 2θ we get
( cos 2θ + sin 2θ ) / cos 2θ = 1 / cos 2θ
1 + sin 2θ / cos 2θ = sec 2θ
And sin 2θ / cos 2θ = tan 2θ
Then
1 + tan 2θ = sec 2θ
we know that
In the right triangle ABC
∠∠ ------> by complementary angles
so
Step
Find the measure of angle B
we know that
in this problem
so
Step
Find the measure of angle A
therefore
the answer is the option
35.5° and 54.5°
