What is the sum of angles of quadrilateral?

The sum of the angles of the quadrilateral is 360 degrees.

We need to find the ∠BCA:

∠OBD = 90  

∠OAD = 90  

So angles in quadrilateral BOAD

56, 90, 90 and∠ BOA

56 + 90 + 90 + ∠BOA = 360

∠BOA = 360 - 90 -90 - 56

∠BOA = 124

∠BCA is angle at circumference

∠BOA = 124, is the angle at centre

Angle at Centre = 2 x Angle at circumference

Angle at Circumference = Angle at Centre / 2 = 124/2 = 62

∠BCA = 62 degrees

thus, Option B. is correct.

A student claims that the expression “9 times the sum of a number and 13" is translated to the algebraic expression 9n + 13. Is the student correct? If not, what is the correct expression?​

Answers

Answer:

No, the student is not correct. The correct expression is 9(n+13).

Step-by-step explanation:

"9 times the sum of a number and 13" means you must multiply 9 by the sum, not just by the number. 9n + 13 would be "the sum of 9 times a number and 13." Slightly different wording.

Answer:

Sample Response: The student is not correct. He should use parentheses like this 9(n+13). Without the parentheses, it means nine times n plus 13, but should be the sum of n plus 13 multiplied by 9.

What is an arc measure of a circle?

'An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc. This angle measure can be in radians or degrees.'

According to the the given problem,

If we draw a dotted line from H to P and from J to P,

∠HKP = ∠JLP (Similarity of triangles)

HP = JP

KP = LP

⇒ ΔHKP ≅ ΔJLP

⇒ KH = LJ

Now, joining G and P,

GP = HP (radius of the circle)

PM is perpendicular to GH.

⇒ PM equally divides GH .

⇒ KH = GK = [tex]\frac{1}{2}[/tex] of GH

          = [tex]\frac{1}{2}[/tex] × 36

          = 18 feet

Hence, we can conclude that the length of LJ is 18 feet.

Answer:

  C  3x +1 = y

Step-by-step explanation:

x-values increase by 1 from row to row.

y-values increase by 3 from row to row.

The slope of the linear function is the ratio of the y-increase to the x-increase:

  m = ∆y/∆x = 3/1 = 3

The only offered choice with an x-coefficient of 3 is ...

  C  3x +1 = y

__

If you check this against the table entries, you find it fits.

  3(1) +1 = 4

  3(2) +1 = 7

and so on.

Answers

Answer:

y = 3/2x + 7/2

Step-by-step explanation:

First, you need to find the slope.

y2 - y1 / x2 - x1

= 5 - 8 / 1 - 3

= 3/2

The slope is 3/2x.

To find the y-intercept, plug any one of the coordinates into the equation, which is y = 3/2x + b

y = 3/2x + b

8 = 3/2(3) + b

8 = 9/2 + b

7/2 = b

The equation y = 3/2x + 7/2.
