Question

1
25) Prove that
cos(x-a)cos (x-b)
tan(x-b-tan (x-a)
sin (a-b)​

Answer 1

Answer:

This can be solved easily once we visualise it.

Explanation:

A)wkt, tanx = perpendicular(p)/base(b) .....(1)

B)We are given tanx=5/12 .....(2)

C)On comparing the quantities we get that p=5 and b=12

D)We require the value of hypotenuse(h),

for this we apply the Pythagoras theorum i.e,

h 2=p 2+b2

⇒h 2 =52+122

⇒h 2=25+144

⇒h2

=169⇒ h=√169

⇒h=13
