Question

find ab(ac=17 cm ,bc= 8 cm ,

Answer 1

Answer:

Tan c= 8/15

sec a= 17/8

cosec c=17/8

cot a =8/15

Answer 2

Answer:

Let the ab be x.

By Pythagoras theorem

a² = b² + c²

ac² = bc² + ab²

17² = x² + 8 ²

289 = x² + 64

289 - 64 = x²

225 = x²

√225 = x

15 = x.

hence ,ab is equal to 15cm.
