Answer:

$\boxed{\textsf{ The LCM of 56 , 42 , 28 is \textbf{ 168}.}}$

Step-by-step explanation:

We need to find out the LCM of 56 , 42 , 28 . So Lowest Common Multiple known as LCM is the lowest multiple which is divisible by all the numbers whose LCM is taken out . It can we done by two methods. Both of which are discussed in the attachment .

For complete solution kindly refer to the attachment .

Related Information :- 

• HCF :-

It stands for Highest Common Factor . It is the highest numbers which divides out completely the numbers without leaving remainder of the numbers whose HCF is we are finding out .

M < PQS + m < RQS = 180° because they are supplementary angles.

Therefore:
(3x + 3) + (x + 19) = 180

3x — 3 + x + 19 = 180

4x + 16 = 180

Subtract 16 from both sides

4x — 16 = 180 — 16

4x = 164

Divide both sides by 4:

4x/4 = 164/4

x = 41

Therefore, the correct answer is x = 41

Consider the parametric curve:

11Alexandr11 [23.1K]

By the chain rule,

$\dfrac{\mathrm dy}{\mathrm dx}=\dfrac{\frac{\mathrm dy}{\mathrm dt}}{\frac{\mathrm dx}{\mathrm dt}}=\dfrac{4\sec t\tan t}{3\sec^2t}=\dfrac43\sin t$

When $t=\pi$ , we have

$\dfrac{\mathrm dy}{\mathrm dx}\bigg|_{t=\pi}=\dfrac43\sin\pi=0$
