From a point 80 m along level ground from the base of a tower, the angle of elevation to a cat sitting on the top of the tower is 28°. How high above the ground is the cat

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

this answer is !

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
