Quadrilateral WXYZ is a rhombus. What is the measure of < XWZ?
den301095 [7]

Answer:

<XWZ=52°

Step-by-step explanation:

By alternate angle property, < XZY=<WXZ=64°

The base angles of an isosceles triangle are also equal therefore

<WXZ=<WZX=64°

The sum of angles in a triangle is 180°

< XWZ+<WXZ+<WZX=180°

<XWZ+64+64=180°

<XWZ=180°-64-64

This simplifies to

<XWZ=52°

Please help me asap. Got stuck with this question
Temka [501]

Answer:

Step-by-step explanation:

a.\\\frac{d}{dx}(\frac{-1}{1+x^2} )=\frac{d}{dx} [-1(1+x^2)^{-1}]=-1(-1)(1+x^2)^{-2}(2x)=\frac{2x}{(1+x^2)^2 }\\

b.

put 1+x²=u

2x dx=du

when x=0,u=1

when x=2,u=1+2²=5

\int\limits^5_1 {\frac{1}{u}} \, du= ln |u| ,1 \to 5=ln5-ln1=ln 5-0=ln 5

How long will it take to fill the pool if two hoses are used, one that fills at a rate of 40 gallons per hour and one that fills
aalyn [17]
<h3>Answer:</h3>

Your selection is correct: 180 hours

<h3>Step-by-step explanation:</h3>

The pool is apparently 18000 gallons (= 60 gal/h × 300 h). The combined flow from the two hoses is ...

... (40 gal/h) + (60 gal/h) = 100 gal/h

So, the time required with the two hoses is ...

... 18000 gal/(100 gal/h) = 180 h

ANSWER

B. 10

EXPLANATION

We need to find the value of x first.

It was given that the perimeter of triangle XYZ is 24.

This means that:

XY+YZ+XZ=24

we substitute the expression in terms of x to get;

(5x - 1) + (13 - x) = 24

This implies that

5x - x = 24 - 13 + 1

4x = 12

Divide both sides by 4 to get;

x = 3

|WY|=|ZX|=13-3=10
