Question

What is the sin x, cos x and tan X

Answer 1

c. cos(x)=13/20, sin(x)=11/20, tan(x)=11/13

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
