ANSWER
The fiftieth term is 286.
EXPLANATION
A sequence with a common difference,

is an arithmetic progression.
The nth term is

If the sixth term is 22 then,




The fiftieth term is



since the distance from the outside edges is 26 1/2 feet, divide that by 2 to get the distance from the center to the edge ( 26 1/2 / 2 = 13 1/4 feet)
the stage is 76 feet so divide that by 2 to find the center 76/2 = 38 feet
now subtract the 13 1/4 from 38
38 - 13 1/4 = 24 3/4 feet from the side of the stage to the edge of the trap door
a little easier way would be to subtract the 26 1/2 from 76 and then divide by 2
76-26 1/2 = 49 1/2 / 2 = 24 3/4
Answer:
i. sin(C) = 
ii. tan(C) = 
iii. sin(B) = 
Step-by-step explanation:
Given a right angled triangle ABC, with a right angle at A.
<ABC = 
<BCA = 
AC = 9 = 1
CB = 18 = 2
Applying Pythagoras theorem to ΔABC, we have;
AB = 
= 
= 
Thus applying the trigonometric ratios, it would be observed that;
i. sin(C) = 
ii. tan(C) = 
iii. sin(B) = 
It's simple.
