<h2>QUESTION :</h2>

Find x in the given quadrilateral.

X

120°

80°

60°

<h3>CHOICES</h3>

a. 100°

b. 120°

c. 150°

d. 180°

<h2>ANSWER:</h2>

\boxed{\sf A.100}

<h3>Solution:</h3>

\begin{gathered}\rightarrow\boxed{\sf 120+80+60+x=360 } \\ \rightarrow\boxed{\sf x=360-260 } \\ \rightarrow\boxed{\sf x=\blue1\blue0\blue0 }\end{gathered}

To find x in quadrilaterals, Firstly let's say the given quadrilaterals, So the result is 360, then subtract it by 260 maybe when you say 3 numbers it the result is 260.Therefore the answer is 100

If x² + xy – 3y = 3, then at the point (2, 1), dy/dx
Scilla [17]

Answer:

A

Step-by-step explanation:

We have the equation:

x^2+xy-3y=3

Take the derivative of both sides with respect to x:

\frac{d}{dx}[x^2+xy-3y]=\frac{d}{dx}[3]

Implicitly differentiate:

2x+y+x\frac{dy}{dx}-3\frac{dy}{dx}=0

Solve for dy/dx:

\frac{dy}{dx}(x-3)=-2x-y\\

Divide:

\frac{dy}{dx}=-\frac{2x+y}{x-3}

To find dy/dx at (2, 1), substitute 2 for x and 1 for y. So:

\frac{dy}{dx}_{(2, 1)}=-\frac{2(2)+1}{2-3}=-\frac{5}{-1}=5

Hence, our answer is A.

Zina [86]

Answer:

B) 47.5%

Step-by-step explanation:

Refer to the normal distribution chart attached. If 130 is 2 standard deviations higher than the mean (ignore the numbers beneath the percentages), then by the empirical rule, this means that 34%+13.5%=47.5% of adults are between IQs of 100 and 130. Therefore, option B is correct.

What do you do when your mom is crying? probably not the best place to ask but im grounded so i cant ask on any other platform l
FromTheMoon [43]

Answer:

Ask her why she is crying. If she explains why, listen and comfort her. If she says to "go away" or "i don't want to talk about it," give her space and come back later. She needs to let it out, so have patience :)

Hope this helps!!
