Chapter 8: Q.4 (page 553)

Find an exact value of each expression, without using a calculator $\frac{s e c 55}{c s c 35}$

Short Answer

Expert verified

The simplified value is $1$

Step by step solution

Step 1. Given information

The given expression is $\frac{s e c 55}{c s c 35}$

Step 2. Convert into the same trigonometrical ratio

The given expression is $\frac{s e c 55}{c s c 35}$

$s e c (90 - θ) = c s c θ$

Now $= \frac{s e c 55}{c s c 35} = \frac{s e c (90 - 35)}{c s c 35} = \frac{c s c 35}{c s c 35} = 1$

Step 3. Conclusion

Hence, the simplified value is $1$
