Step-by-step explanation:
a+(a+60)=760
a=adult tickets
a+60=student tickets
a+a+60=2a+60
2a+60=760
-60 -60
2a=700
÷2. ÷2
a=350
350 adult tickets
see the attached figure to better understand the problem
we know that
The Area of the composite figure is equal to the sum of Area 1, Area 2 and Area 3
The Area 1 is a triangle
The Area 2 is a rectangle
The Area 3 is equal a semicircle
therefore
<u>the answer is the option</u>
a triangle, a rectangle, and a semicircle
Sin = opposite/hyp
Sin A = 10/26 = 5/13
Sin b = 24/26 = 12/13
The answer is option A
Hope this helps
Area yellow =11 x 6
= 66
red area = 7 x 2
=14
area of yellow
66 - 14 = 52
