Sagot :

Answer:

[tex]\cos(T)[/tex] =[tex]\frac{\sqrt{15}}{5}[/tex]

Step-by-step explanation:

Given parameters.

[tex]TU = 4\sqrt 5[/tex]

[tex]SU = 4\sqrt 2[/tex]

[tex]ST = 4\sqrt 3[/tex]

Required

Determine [tex]\cos(T)[/tex]

Reference to [tex]\angle T[/tex], we have:

[tex]Opposite = 4\sqrt 2[/tex]

[tex]Adjacent = 4\sqrt 3[/tex]

[tex]Hypotenuse = 4\sqrt 5[/tex]

Apply trigonometry ratio of cosine

[tex]\cos(T)[/tex] [tex]= \frac{Adjacent}{Hypotenuse}[/tex]

Substitute values for Adjacent and Hypotenuse

[tex]\cos(T)[/tex] [tex]= \frac{4\sqrt 3}{4\sqrt 5}[/tex]

[tex]\cos(T)[/tex] [tex]= \frac{\sqrt 3}{\sqrt 5}[/tex]

Rationalize:

[tex]\cos(T)[/tex] [tex]= \frac{\sqrt 3}{\sqrt 5}*\frac{\sqrt 5}{\sqrt 5}[/tex]

[tex]\cos(T)[/tex] =[tex]\frac{\sqrt{15}}{5}[/tex]
