Sum

In the right angled △ XYZ, ∠XYZ = 90° and a, b, c are the lengths of the sides as shown in the figure. Write the following ratios,

(i) sin X (ii) tan Z (iii) cos X (iv) tan X.

SOLUTION

(i) Sin X =

Opposite side of ∠ XHypotenuse =

YZXZ =

ac

(ii) tan Z =

Opposite side of ∠ ZAdjacent Side of ∠ Z =

XYYZ =

ba

(iii) Cos X =

Adjacent Side of ∠ ZHypotenuse =

XYXZ =

bc

(iv) tan X =

Opposite side of ∠XAdjacent Side of ∠X =

YZXY =
