Angle θ is in standard position. If (8, -15) is on the terminal ray of angle θ, find the values of the trigonometric functions. sin(θ) =
✔ -15/17

cos(θ) =
✔ 8/17

tan(θ) =
✔ -15/8

csc(θ) =
✔ -17/15

sec(θ) =
✔ 17/8

cot(θ) =
✔ -8/15

Arley is building a model of a city map. in one part of the city, three roads form a right triangle, which harley draws as triangle abc, with the following measures: m∠b=90° and m∠a=30°. in his scale model, the hypotenuse of triangle abc, ac¯¯¯¯¯¯¯¯, has a length of 817−−√ cm. what is the value of a (the length of bc¯¯¯¯¯¯¯¯)?

I'm confused on this could anyone me and show me what i need to do to solve it.
