Question

Plz plz plz plz help ​

Answer 1

Here sin28 = perpendicular/hypotenuse

AC = sin28 * 3

AC = 0.46*3

AC = 1.38

Answer 2

AC is 6.5 cm

Explanation:

From trigonometric ratios:

`\sin( \theta) = (opposite)/(hypotenuse) \\`

opposite » 3 cm

hypotenuse » AC

angle » 28°

`\sin(28 \degree) = (3)/(AC) \\ \\ AC = (3)/( \sin(28 \degree) ) \\ \\ AC = (3)/(0.46) \\ \\ AC = 6.5 \: cm`
