x = 11.8

y = 2.1

Explanation:

We apply the trigonometry ratio SOHCAHTOA

The hypotenuse = 12cm

adjacent = base = y

The opposite (side opposite the angle) = x

The angle = 80 degrees

To get x, we apply sine ratio (SOH)

sin 80 = opposite/hypotenuse

sin 80 = x/12

x = 12 × sin80

x = 12 = 0.9848

x = 11.8176

To the nearest tenth, x = 11.8

To get y, we apply cosine ratio (CAH)

cos80 = adjacent/hypotenuse

cos80 = y/12

y = ×12 cos80

y = × 12 0.1736

y = 2.0832

To the nearest tenth, y = 2.1
