Answer 1

Answer:

• C. 4/5

Step-by-step explanation:

• cos  = adjacent / hypotenuse
• cos (M) = MN / ML = $\sqrt{ML^2 -NL^2 }$/ML = $\sqrt{25^2-15^2}$/25 = 20/25 = 4/5

Correct choice is C

Answer 2

Answer:

→ cos∅ = base/hypotenuse

→ cos(M) = MN/ML

→ MN = √(ML²-NL²)

= √(25²-15²)

= √(625-225)

= √400

= 20

→ML = 25

Therefore, cos(M) = 20/25 = 4/5

• 4/5 is the right answer.
