Question

If 17 cos theta=15 find tan theta+2sectheta

Answer 1

Answer:

The required answer is 2(4/5)

Step-by-step explanation:

17cosΘ=15

17cosΘ=15cosΘ=15/17

cosΘ=B/H=15/17

Now, using Pythagoras Theorem,

H^2=P^2+B^2

17^2=P^2+15^2

P=8

Now, tanΘ+2secΘ

=P/B+2( H/B)

= 8/15+2(17/15)

=8+34/15

=42/15

=(2)4/5
