Given right triangle mnl, what is the value of cos(m)?

This is what i found hope it helps

Find the value of MN

In the right triangle MNL

Applying the Pythagorean Theorem

Solve for MN

in this problem we have

Substitute in the formula above

Step

Find the value of cos (M)

we know that

In the right triangle MNL

Substitute the value of MN

therefore

the answer is

The value of cos(M) is

, 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

c
