Answer:

$\cos\ A = \frac{2}{4.5}$

Step-by-step explanation:

Given

$sin\ A = \frac{2}{4.5}$

See attachment

Required

Explain and correct the error

The error in the equation is that: the formula of cosine of angle A is used to calculate the sine of angle A.

The ratio can be corrected as by using:

$\cos\ A = \frac{Adjacent}{Hypotenuse}$

$\cos\ A = \frac{AC}{AB}$

$\cos\ A = \frac{2}{4.5}$

Could someone please help me solve this?

Answer:

Step-by-step explanation:

(2/5)*n - 6 = 10 Add 6 to both sides

(2/5)*n - 6 + 6 = 10 + 6 Combine

(2/5)*n = 16 Multiply both sides by 5/2

(5/2)(2/5)n = 16*(5/2)

n = 80 / 2

n = 40
