Answer 2

Answer:

Step-by-step explanation:

1. ( iii)

L.H.S---

( Sin 26⁰ / sec 64⁰ ) +

( cos 26⁰ / cosec 64⁰)

= sin 26⁰ / sec ( 90⁰ - 26⁰ ) +

cos 26⁰ / cosec ( 90 - 26) ⁰

= sin 26⁰ / cosec 26⁰ +

cos 26⁰ / sec 26⁰

= sin 26⁰ × sin 26⁰ +

cos 26⁰ × cos 26⁰

= Sin ² 26⁰ + cos ² 26⁰

= 1 = RHS

As, sin² ∅ + cos ² ∅ = 1
