X=109

The polygon has 5 sides which makes it a pentagon

The sum of all of the angles of a pentagon equal 540 degrees.

Add all given angles (431 degrees)

Subtract 431 from 540 and you will get 109 which is X

Prove the following identity <br><br><br> sin x(sec x+cscx)= tan x +1

Alexxandr [17]

Answer:

Step-by-step explanation:

<u>________________________________________________________</u>

<u>FACTS TO KNOW BEFORE SOLVING :-</u>

<u></u> $\sin x = \frac{1}{cosec \: x} \: \: or \: \: cosex \: x = \frac{1}{\sin x}$ <u></u>

<u></u> $\cos x = \frac{1}{\sec x} \: \:or \: \: \sec x = \frac{1}{\cos x}$ <u></u>

<u></u> $\tan x = \frac{\sin x}{\cos x}$ <u></u>

<u>________________________________________________________</u>

In the question ,

L.H.S. = $\sin x (\sec x + cosec \: x)$

R.H.S. = $\tan x + 1$

Lets solve L.H.S. first.

$\sin x (\sec x + cosec \: x)$

$=> \sin x( \frac{1}{\cos x} + \frac{1}{\sin x} )$

$=> \frac{\sin x}{\cos x} + \frac{\sin x}{\sin x}$

$=> \tan x + 1$

∴ L.H.S. = R.H.S. (Proved)

What is the probability that a randomly chosen number 1 to 100 is not a multiple of 5? Express the answer as a percent or fracti

Svetradugi [14.3K]

Answer:

80% or 4/5

Step-by-step explanation:

So there are 20 multiples of 5 in 100

so the possibility of not choosing 20 out of 100 is 80/100
