Given right triangle mnl, what is the value of cos(m)?
a. 3/5
b. 3/4
c. 4/5
d. 5/3

C. 4/5

Step-by-step explanation:

We have that cos(M) = Adjacent side/Hypotenuse

Where:

Hypotenuse (h) = 25

We do not know the adjacent side (a), but the opposite side (b).

Then we use the Pythagorean theorem:

Then:

Option C

The correct answer is option C. 4/5

Step-by-step explanation:

Pythagorean theorem:-

Hypotenuse² = Base² +  Height²

It is given a right triangle ABC.

To find the value of MN

Hypotenuse² = Base² +  Height²

ML = 25

NL  =15

MN = ?

ML²  = NL² + MN²

MN² = ML² - NL² =  25² - 15² = 625 - 225 = 400

MN = √400 = 20

To find Cos(M)

Cos(M) = Adjacent side/Hypotenuse

Cos(M) = MN/ML= 20/25 = 4/5

The correct answer is Option C. 4/5

there are 25 people coming to the party

step-by-step explanation:

the text says that there will be 22 children at this party, 1 teacher, and 2 parents. so if you add them all together (22+1+2) it will equal 25. (=25)
