Solution

Note: Area of Kite

From the question we have

\begin{gathered} Area=\frac{1}{2}\times10\times2y \\  \\ 20=10y \\  \\ y=2 \end{gathered}

Therefore, y = 2

How do you go about doing this surface area problem?

Break it down into 2-Dimensional shapes. Then add the areas together.

From the picture you can see;
front & back rectangles are 2*(4 x 8) = 64 m²
2 side rectangles are 2*(4 x 12) = 56 m²
2 triangular front & back pieces are (1/2)*8*3 = 12 m²
2 roof rectangles are 2*(5 x 12) = 120 m²

total Surface area = 64 m² + 56 m² + 12 m² + 120 m²
= 252 m²

For the volume; break it up into 3-dimenssional shapes and add the volumes together.

From the picture you can see;
Rectangular box volume is 4 x 8 x 12 = 384 m³
Triangular roof volume is area of front triangle multiplied through the length. (1/2)*8*3* 12 = 144 m³

Total volume = 384 m³ + 144 m³
= 528 m³

I need help this is a tangent and secant problem and I'm confused
Luda [366]
<h3>Answer:   110 degrees</h3>

======================================================

Work Shown:

x = measure of minor arc CL

angle J = ( (far arc) - (near arc) )/2

angle J = ((red arc) - (yellow arc))/2

angle J = ( (minor arc CL) - (minor arc CK) )/2

35 = ( x - 40 )/2

35*2 = x-40

70 = x-40

x-40 = 70

x = 70+40

x = 110

Minor arc CL = 110 degrees

PLEASE HELP!! NO LINKS!! GIVING 20 POINTS AWAY!!
shutvik [7]

Answer:

m\angle N = 32\degree

m\widehat {NQ}=106\degree

Step-by-step explanation:

By inscribed angle theorem:

m\angle N = \frac{1}{2} \times m\widehat {MP}

m\angle N = \frac{1}{2} \times 64\degree

m\angle N = 32\degree

Again by inscribed angle theorem:

m\angle P= \frac{1}{2} \times m\widehat {NQ}

53\degree = \frac{1}{2} \times m\widehat {NQ}

2\times 53\degree = m\widehat {NQ}

m\widehat {NQ}=106\degree

Write the following using algebraic notation, using the letter x for any unknown numbers:
Mnenie [13.5K]

Answer:

\dfrac{x+7}{5}

Step-by-step explanation:

The given statement is "I think of a number, add seven then divide by five".

Let the unknown number be x.

Now, add 7 to the number = x+7

If we divided them by 5, \dfrac{x+7}{5}.

So, the required algebraic notation is  \dfrac{x+7}{5}.
