Question

Kindly give the answer with full steps. ​

Answer 1

Answer:

Step-by-step explanation:

//We know by definition that Cosθ = Adjacent side to θ/ Hypotenuse.

Cosα = 5/13

But in ΔABC,

Cosα = BC/AC = 5/13

=> BC = 5 cm and AC = 13 cm.

Similarly in ΔCED,

Cosβ = 3/5 = CD/CE

=> CD = 3 cm and CE = 5 cm.

Thus length of BD = BC + CD = 5 + 3 = 8 cm.
