1.	Pls find the angle measure x in the figure. ☝️
Answer» Step-by-step explanation: total ANGLE MEASURE = 480 (property) 30+110+120+2x=480 (180-70=110 and 180-60=120) THEREFORE 260+2x=480 2x=480-260 2x=220 x=110

1.

Pls find the angle measure x in the figure. ☝️

Answer»

Step-by-step explanation:

total ANGLE MEASURE = 480 (property)

30+110+120+2x=480

(180-70=110 and 180-60=120)

THEREFORE 260+2x=480

2x=480-260

2x=220

x=110

In the figure AB//CD the value of x+y is

Answer»

<P>Answer:

Answer:

x = 20

y = 60

z = 120

Step-by-step explanation:

AB ║ CD

=> ∠CPQ = ∠PQR

=> ∠CPQ = 80°

80° + 2x° + 3x° = 180° (Straight line)

=> 5x° = 100°

=> x = 20

80° + 2x° + y° = 180° (sum of angles of a TRIANGLE)

=> 40° + y° = 100°

=> y° = 60°

=> y = 60

y° + z° = 180° (Straight line)

=> 60° + z° = 180°

=> z° = 120°

=> z = 120

15.	Which factors does differ ?
Answer» Questions: What is a factor? ANSWER: As defined above, a factor is a number that divide a certain number to give out a whole number or integer. Step-by-step explanation: For EXAMPLE, 2 is a factor of 8 because it DIVIDES 8 WITHOUT LEAVING any remainder. 1 is the smallest factor of any number. The factors of 8 are therefore 1, 2, 4 and 8 itself. When listing factors of a given number, the first step is to identify all numbers that divide this particular number without a remainder. And to do so, 1 is listed as the first minimum factor. For example, the factors of a number are integers which divide that particular number without a remainder. The number 16 has five factors: 1, 2, 4, 8 and 16. If number 16 is divided by any of the five numbers, then the resultant is a whole number

Radius of circle is 20cm and distance of a chord form the centre is 12 CM the length of a chord is

Answer»

GIVEN A CIRCLE with center O Radius OA=10 cm CHORD AB=12 cm.

To find the distance OM of the chord from O

OM is PERPENDICULAR to chord AB

As perpendicular from the center Na chord bisect the chord. So AM= AB/2 =6 cm

In right angled triangle AMO

AO² =AM² +OM²

⇒10² =6² +OM²

⇒100=36+OM²

⇒OM² =100−36

Answer» Step-by-step EXPLANATION: If two lines are parallel then they have the same slope The slope of the X axis is ZERO ( the equation of x axis is y=0), therefore slope of the line is zero slope of a any line = Y2-y1/ x2-x1 Let point (-7,-3) be (x1, y1) Let (x2, y2) be another point on the line then 0 = y2-3/x2-7 0=y2-3 y2 = -3 Therefore the equation of the line is y=-3 If you draw the line y=-3 you will notice it is parallel to the x-axis and passes through (-3,-7

26.

I'm quite confused. Please help me with this one, too!

Answer»

Step-by-step EXPLANATION:

If two lines are parallel then they have the same slope

The slope of the X axis is ZERO ( the equation of x axis is y=0), therefore slope of the line is zero

slope of a any line = Y2-y1/ x2-x1

Let point (-7,-3) be (x1, y1)

Let (x2, y2) be another point on the line

then 0 = y2-3/x2-7

0=y2-3

y2 = -3

Therefore the equation of the line is y=-3

If you draw the line y=-3 you will notice it is parallel to the x-axis and passes through (-3,-7

Find the value of (i) x 3 + y 3– 12xy + 64, when x + y = – 4 (ii) If x + y = 12 and xy = 27, find the value of x3+ y3

Answer»

Answer:

i) (x,y) = (-36 , 32)

ii) (x,y) = (5.2 , 140.4)

Step-by-step EXPLANATION:

GIVEN :- i)x³ + y³ - 12xy +64 = 0 and x+y= -4

ii) x+y = 12 and XY = 27 and x³+y³= 0

TO FIND :- value of 'x' and 'y'

SOLUTION :- i) x³ + y³ - 12xy +64 = 0 -----(I)

x+y= -4 ------------------------(II)

∴ x = - (4+y) ---------------------[from equation no.(II)]-----(III)

Now, putting x = -(4+y) in equation no.(I)

[-(4+y)]³ + y³ -12[-(4+y)]y + 64 = 0

∴ -64 + y³ + 48 - 12y² + 64 = 0

∴ y - 12 + 48 = 0

∴ y = -36

∴ Putting y = -36 in equation no.(III)

x = - [4 + (-36)]

∴ x = 32

∴ (x,y) = (-36 , 32)

--------------------------------------------------------------------------------------------------------------

ii) x+y = 12 -----------(I)

xy = 27 -------------(II)

x³+y³= 0 -----------(III)

Now,

x² = -y² ------[from equation no.(III)------(IV)

Now,

x = 27 / y

∴ squaring on both SIDES, we get

x² = 729 / y² ----------(V)

Now, Putting equation no. (V) in equation no. (IV)

729 / y² = -y²

∴ y∧4 = 729

∴ taking 4th root, we get

y = 5.2

Now, putting y = 5.2 in equation no.(III)

x × 5.2 = 27

∴ x = 27 / 5.2

∴ x = 140.4

∴ (x,y) = (5.2 , 140.4).
