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:

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

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

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

Solve the equation 0.25 (8z - 4) = z + 8 - 2z

Andrew [12]

Distribute
2z-1=z+8-2z
add like terms
2z-1=-z+8
add z to both sides
3z-1=8
add 1 to both sides
3z=9
divide both sides by 3
z=3
