Answer:

Area of trapezium = 4.4132 R²

Step-by-step explanation:

Given, MNPK is a trapezoid

MN = PK and ∠NMK = 65°

OT = R.

⇒ ∠PKM = 65° and also ∠MNP = ∠KPN = x (say).

Now, sum of interior angles in a quadrilateral of 4 sides = 360°.

⇒ x + x + 65° + 65° = 360°

⇒ x = 115°.

Here, NS is a tangent to the circle and ∠NSO = 90°

consider triangle NOS;

line joining O and N bisects the angle ∠MNP

⇒ ∠ONS = \frac{115}{2} = 57.5°

Now, tan(57.5°) = \frac{OS}{SN}

⇒ 1.5697 = \frac{R}{SN}

⇒ SN = 0.637 R

⇒ NP = 2×SN = 2× 0.637 R = 1.274 R

Now, draw a line parallel to ST from N to line MK

let the intersection point be Q.

⇒ NQ = 2R

Consider triangle NQM,

tan(∠NMQ) = \frac{NQ}{QM}

⇒ tan65° = \frac{NQ}{QM}

⇒ QM = \frac{2R}{2.1445}

QM = 0.9326 R .

⇒ MT = MQ + QT

          = 0.9326 R + 0.637 R  (as QT = SN)

⇒ MT = 1.5696 R

⇒ MK = 2×MT = 2×1.5696 R = 3.1392 R

Now, area of trapezium is (sum of parallel sides/ 2)×(distance between them).

⇒ A = (\frac{NP + MK}{2}) × (ST)

       = (\frac{1.274 R + 3.1392 R}{2}) × 2 R

       = 4.4132 R²

⇒ Area of trapezium = 4.4132 R²

Convert each equation to standard form y-5=-3(x+2)​
ale4655 [162]

You said each equation but only posted one.

The standard form takes the place of

Ax + By = C.

y-5 = -3(x+2)​

y - 5 = -3x - 6

y = -3x - 6 + 5

3x + y = -1

Done.

How can you use the point-slope form of a line when only given two points?
pshichka [43]

Answer:

See below

Step-by-step explanation:

<u>Point -slope form is:</u>

  • y - y1 = m(x - x1)

By having one set of coordinates and knowing the value of the slope (m in the equation) you can use the form.

<u>How to find the slope?</u>

Here you need 2 points: Point 1 with coordinates x1, y1 and point 2 with the coordinates x2, y2

<u>Use the formula:</u>

  • m = (y2-y1)/(x2-x1)

<u>Example:</u>

  • m = -5, and one of the points has coordinates (9, 2) then point-slope form is:
  • y - 2 = -5(x - 9)
