pls help me with my homework i dont understand

Answer:
u ≈ 3.4 , t ≈ 7.3
Step-by-step explanation:
using the cosine ratio in the right triangle
cos65° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{u}{8}[/tex] ( multiply both sides by 8 )
8 × cos65° = u , then
u ≈ 3.4 ( to the nearest tenth )
using the sine ratio in the right triangle
sin65° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{t}{8}[/tex] ( multiply both sides by 8 )
8 × sin65° = t , then
t ≈ 7.3 ( to the nearest tenth )
