Class Tenth Question with Answer?? trigonometry questions for class 10 ncert


Answer -----

tan?=8/15 = (p/b),...

given value is - p = 8
b= 15,

h = ??

h^2= p^2+ b^2
= (8)^2 + (15)^2
= 64+225
=289
h= 17

..................
1+cos^2? = 1+ (b/h)^2
= 1+ (15/17)^2
= 1+225/289
= 514/289

ans............
