Can someone solve this?

Step-by-step explanation:

1. The total of central angles in a circle is 360°. The smaller sector (and the arc subtended) has measure 360° -210° = 150°.

The area is given by the formula ...

  A = (1/2)r²θ . . . . where θ is in radians

150° = (150/180)π radians, so the area of the smaller sector is ...

  A = (1/2)(12 in)²(5π/6) = 60 in²

__

2. The measure of an inscribed angle is half the measure of the arc it subtends. θ subtends an arc of 90°, so has measure 90°/2 = 45°.

__

3. LQ is the perpendicular bisector of MP, so ...

  MT = TP

  5x -6 = 2x +9

  3x = 15 . . . . add 6-2x

  x = 5

__

4. Tangents to the same circle from the same point are equal length.

  AB = AD

  3x +10 = 7x -6

  16 = 4x . . . . . . . add 6-3x

  4 = x

__

5. The standard form is ...

  (x -h)² +(y -k)² = r²

Comparing to the given equation, we see ...

The center is (h, k) = (-2, 7) (choice B); the radius is 6.

__

6. As in problem 2, the inscribed angle is half the measure of the arc it subtends. In an inscribed quadrilateral, that fact also means that opposite angles are supplementary.

  angle 2 = (64° +90°)/2 = 77°

  angle 3 = 180° -95° = 85°

  angle 4 = 180° -77° = 103°

__

7. Chords of the same length are the same distance from the center of the circle:

  3x +1 = x +8

  2x = 7 . . . . subtract x+1

  x = 3.5

__

8. You can work this problem several ways, or you can simply "cut to the chase." The measure of x is the supplement of the subtended arc.

  x = 180° -117°

  x = 63°

You can also use the fact that the tangents make right angles with the radii and the sum of angles of a quadrilateral is 360°. That gets you to ...

  117° +90° +x° +90° = 360°

  x = 180° -117°

Or, you can use the fact that the external angle (x°) is half the difference of the long arc and short arc:

  x° = (1/2)((360° -117°) -117°) = (1/2)(360° -2(117°)) = 180° -117°

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.

dont trust me im no expert these losers made me fail a test bro this sucks
