5.

in the figure a says the angle bisector of angle b A b if ab is equal to a day then prove that B is equal to CD

Answer»

lLet the common ratio between a and b be x.

∴ a = 2X, and b = 3x

XY is a straight line, rays OM and OP stand on it.

∴ ∠XOM + ∠MOP + ∠POY = 180º

b + a + ∠POY = 180º

3x + 2x + 90º = 180º

5x = 90º

x = 18º

a = 2x = 2 × 18 = 36º

b = 3x= 3 ×18 = 54º

MN is a straight line. Ray OX STANDS on it.

∴ b + C = 180º (Linear Pair)

54º + c = 180º

c = 180º − 54º = 126º

∴ c = 126º

13.

The ratio of two numbers is1/2. If 2 is subtracted form the first and 8 from the.second, the ratio became reciprocal of the original ratio. Find the numbers.

Answer»

Step-by-step explanation:

let the first NUMBER be X.

let the second number be Y.

original equation will be :-

X/Y=1/2

Y=2x

THEREFORE, according to questions:-

X-2/Y-8 = 2/1

X-2 = 2(Y-8)

X-2 = 2Y-16

x-2 = 2(2x) -16

x-2 = 4x-16

-2+16 = 4x-x

14 = 3x

x= 14/3

y= 2(14/3) = 28/3

Find the point on x-axis which is equidistant from the points (2.-2) and (-4.2)

Answer»

<P>Step-by-step explanation:

Let the point on the x−axis be P(a,0)

Let the other two point be A(−2,5) and B(2,−3)

So by distance FORMULA we have,

Distance between two POINTS = (x2−x1)2+(y2−y1)2

Then,

PA=PB

PA2=PB2

⇒(a+2)2+(0−5)2=(a−2)2+(0+3)2

⇒a2+4+4a+25=a2+4−4a+9

⇒4a+29=−4a+13

⇒ 8a=−16⇒a=−2

Answer» 4X - 19 < 3x/5 – 2 ≤ -2/5 + x, x ∈ R ∴ 4x – 19 < 3x/5 – 2, 4x – 3x/5 < -2 + 19, 17x/5 < 17, x < 5, and 3x/5 – 2 ≤ -2/5 + x 3x/5 – x ≤ -2/5 + 2 -2x ≤ 8 x ≥ - 4 ⇒ -4 ≤ x < 5

42.

Solve the inequation with number line

Answer»

4X - 19 < 3x/5 – 2 ≤ -2/5 + x, x ∈ R

∴ 4x – 19 < 3x/5 – 2,

4x – 3x/5 < -2 + 19,

17x/5 < 17,

x < 5,

and 3x/5 – 2 ≤ -2/5 + x

3x/5 – x ≤ -2/5 + 2

-2x ≤ 8

x ≥ - 4

⇒ -4 ≤ x < 5
