Express secΦ in terms of tanΦ

Sunny_sXe [5.5K]

Answer:

$\sec\theta=\sqrt{1+\tan^2\theta}$

Step-by-step explanation:

The trigonometric identity is :

$\sec^2\theta-\tan^2\theta=1\\\\or\\\\\sec^2\theta=1+\tan^2\theta$

We need to express secθ in terms of tanθ.

The above equation becomes,

$\sec\theta=\sqrt{1+\tan^2\theta}$

Hence, this is the required solution.

Kathleen had a bag of candy-coated chocolates. Of the 55 candies in the bag, 20% were red, 30% were orange, 30% were green, and

Marysya12 [62]

So 20% is 1/5 and 1/5 of 55 is 11. That means there are in total 11 blue candies if 1/5 of them is damaged then technically 2.2 of them are which is kinda weird as it doesn't give whole number

3. Find the missing side lengths. Leave your answers as radicals in simplest form. Show your work to support

7nadin3 [17]

Answer: b=2(square root of 2) and a=4

Step-by-step explanation:

Since this is a 45-45-90 triangle we know that side b is equal to $b=2\sqrt{2}$ .

In a 45-45-90 triangle, the hypotenuse is equal to $x\sqrt{2}$ this means in order to find missing side length a, we have to multiply $(2\sqrt{2})(\sqrt{2})$ this will give us 4

so the missing side lengths are, $b=2\sqrt{2}$ and $a=4$
