No, False. All seats in row 1 are same viewing angle. They are inscribed angles measuring 90 degrees. All the seats on row 1 will have the exact same viewing angle because they form a semi-circle around the stage. these would be inscribed angles that have the endpoints of the stage. They would all be 90-degree agles because the stage creates a semicircle and the endpoints of the stage are all the same.
Given function is

At t= 79.5 degree.
So we can place t= 79.5 in given equation

=

=

=

So elevation equal to 625 meter at t = 79.5 degree.
I don’t know what tou want us to figure out, do you want the simplified answer or what x and y are?
Answer:
8
Step-by-step explanation:
Y×2+3=19
19-3=16
16÷2=8
You subtract the 3 first to get what the number was when doubled. After getting that number you would divide it by 2 to get the number that you thought of.
