किंमत काढा? *
O 8/17
0 17/8
O 15/17
0 17/15​

Answer 1

Answer:

0 17/15

Step-by-step explanation:

cotA = 8/15

cotA = adjacent side/opposite side = 8/15

AB = 8 cm ,BC = 15 cm,AC=?

According to PHYTHAGAROUS THEROM,

(AC)^2 = (AB)^2 + (BC)^2

(AC)^2 = (8)^2 + (15)^2

(AC)^2 = 64 + 225

AC = √64 + 225

AC = √289

AC = √17×17 = 17 cm

:. AC = 17 cm

Now,

cosecA = 17/15.
