Hi. Tomorrow on going to get tested on right triangles. I have a problem that I cannot solve.

Can Anyone show me how do you it and give me some examples? Sorry if I'm posting this on a wrong forum.

21. Use cosine:

$\cos (54^{\circ}) = \frac{y}{28} \Rightarrow y = 28 \cos (54^{\circ}) \approx 16.46$ (meters)
