Question

(05.02 LC)
Look at the figure below:an image of a right triangle is shown with an angle labeled y degrees. If sin y° = s/8 and tan y° = s/t, what is the value of sec y°?

Answer 1

• siny=s/8
• tany=s/t

$\\ \tt\longmapsto cosy=\dfrac{siny}{tany}$

$\\ \tt\longmapsto cosy=\dfrac{s/8}{s/t}$

$\\ \tt\longmapsto cosy=8/t$

• Secy=1/cosy=t/8
