Right triangle: relative to acute angle theta, opposite=8 cm, adjacent=15 cm, hypotenuse=17 cm. Define sin(theta)=opposite/hypotenuse, cos(theta)=adjacent/hypotenuse, tan(theta)=opposite/adjacent. Give exact simplified ratios, not an angle approximation. Choosing the other acute angle swaps the two shorter-side names.
