9514 1404 393

Answer:

9/160
9/160

Step-by-step explanation:

Divide each number in the ratio by their greatest common divisor.

4500 : 80000 = (4500/500) : (80000/500) = 9 : 160

8100 : 144000 = (8100/900) : (144000/900) = 9 : 160

In Triangle LMN, < M is a right angle. If MN = 10 and LN = 20.4, determine m < N to the nearest degree.

UNO [17]

cos θ = $\frac{adjacent}{hypotenuse}$

cos ∠N = $\frac{10}{20.4}$

∠N = cos⁻¹ $(\frac{10}{20.4})$

∠N = 60.65°

Answer: 61°
