20 points for this one:))

Answer 1

→ 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.

Answer 2

• C. 4/5

Explanation:

• cos = adjacent / hypotenuse
• cos (M) = MN / ML =
  `√(ML^2 -NL^2 )`/ML =
  `√(25^2-15^2)`/25 = 20/25 = 4/5

Correct choice is C
