Given :-
- First term of an AP is -17 .
- Common difference is 5 .
To Find :-
- The formula for the nth term .
Solution :-
We know that the nth term of an AP is given by ,
where ,
- a is the First term .
- n is the number of the term .
- d is the common difference .
- T_n is the nth term .
On substituting the respective values we have ,
Open the brackets ,
Simplify ,
<u>Hence</u><u> the</u><u> </u><u>nth </u><u>term</u><u> of</u><u> </u><u>the</u><u> </u><u>AP </u><u>is </u><u>given</u><u> </u><u>by </u><u>5</u><u>n</u><u> </u><u>-</u><u>2</u><u>2</u><u>.</u>

Answer:
SMALL ANGLE...30-degrees
LARGE ANGLE...60-degrees
Step-by-step explanation:
SMALL ANGLE...x
LARGE ANGLE...2x
Complementary angles total 90-degrees.
x+2x=90
3x=90
Let's divide both sides by 3...
(3x)/3=90/3
x=30
2x=60
It is B the only one that show proportionality
-16.9x + 16 is the correct answer
