Answer:
c. cos(x)=13/20, sin(x)=11/20, tan(x)=11/13
Step-by-step explanation:
Let θ be an angle in any right triangle:
- sinθ=opposite/hypotenuse
- cosθ=adjacent/hypotenuse
- tanθ=opposite/adjacent
For angle x, opposite=11, adjacent=13, hypotenuse=20. Therefore,
cos(x)=adj/hyp=13/20
sin(x)=opp/hyp=11/20
tan(x)=opp/adj=11/13
⇒Answer choice C
