Answer:

∠ A = 65°

Step-by-step explanation:

The opposite angles of a cyclic quadrilateral are supplementary, sum to 180°

∠ D + ∠ B = 180°, that is

x + 148 = 180 ( subtract 148 from both sides )

x = 32

Thus

∠ A = 2x + 1 = 2(32) + 1 = 64 + 1 = 65°

o-na [289]
<h2>Answer:</h2>

\implies \: x = 46

<h2>Step-by-step explanation:</h2>

<u>By using external angle property</u>,

  • x + x = x + 46
  • 2x = x + 46
  • 2x - x = 46
  • x = 46 <u>Ans.</u>

Note : External angle property theorem is used when <u>sum of other two internal angle is equal to external angle</u>.

What is the equation of a parabola with (4, 6) as its focus and y = 2 as its directrix?
antoniya [11.8K]
So  hmmm if you notice the picture below

bear in mind that, the vertex is "p" distance from the focus, and "p" distance from the directrix

now, the focus is at 4,6 and the directrix below that, meaning the parabola is vertical and opening upwards

and the vertex is half-way between the focus point and the directrix

\bf \textit{parabola vertex form with focus point distance}\\\\&#10;\begin{array}{llll}&#10;(y-{{ k}})^2=4{{ p}}(x-{{ h}}) \\\\&#10;\boxed{(x-{{ h}})^2=4{{ p}}(y-{{ k}})} \\&#10;\end{array}&#10;\qquad &#10;\begin{array}{llll}&#10;vertex\ ({{ h}},{{ k}})\\\\&#10;{{ p}}=\textit{distance from vertex to }\\&#10;\qquad \textit{ focus or directrix}&#10;\end{array}\\\\&#10;-----------------------------\\\\&#10;(x-4)^2=4(2)(y-4)\implies (x-4)^2=8(y-4)&#10;\\\\\\&#10;\cfrac{(x-4)^2}{8}=y-4\implies \cfrac{1}{8}(x-4)^2+4=y

you use 4 gallons of water on 30 plants in your garden. At the rate,how much water will it take to water 45 plants​
astra-53 [7]

Answer:4 gallons of water ... 30 plants

x gallons of water = ? ... 45 plants

If you would like to know how much water will it take to water 45 plants, you can calculate this using the following steps:

4 * 45 = x * 30

180 = 30 * x    /30

x = 180 / 30

x = 6 gallons of water

Result: You will use 6 gallons of water to water 45 plants.
