Neumerical value of tan(20°)×tan(80°)×cot(50°) is equal to?

Answer»

Answer:

0.8390996311

Step-by-step explanation:

TAN(20)=sin20/COS(20)

tan(80)=sin80/cos80=sin(90-20)/cos(90-20)=cos20/sin20

therefor sin20/cos20 * cos20/sin20 =1

=cot(50)*1

18.

What is the perimeter of a rectangle whose length is twice its breadth and the breadth is 7 cm?

Answer»

Given,

BREADTH = 7cm

length of RECTANGLE = 2 × breadth

= 2×7

=14cm

Perimeter of rectangle:

= 2(length+breadth)

= 2(14+7)

= 2 × 21

= 42cm

Thus, the perimeter of a rectangle, whose length is 14cm and breadth is 7cm, will 42cm.

Answer» Answer: 30 Step-by-step EXPLANATION: Number of smaller book MARK packets = 2618/14 = 187 packets. Total number of book marks = 187*25 = 4675 book marks. We know number of ORIGINAL book marks packets = 85 Number of book marks in original pack = 4675/85 = 55. Hence difference in number of book marks in original pack and smaller pack = 55 - 25 = 30.

Answer»

Answer:

30

Step-by-step EXPLANATION:

Number of smaller book MARK packets = 2618/14 = 187 packets.

Total number of book marks = 187*25 = 4675 book marks.

We know number of ORIGINAL book marks packets = 85

Number of book marks in original pack = 4675/85 = 55.

Hence difference in number of book marks in original pack and smaller pack = 55 - 25 = 30.

If the diagonals of a parallelogram are equal in length,show that the parallelogram is a rectangle

Answer»

Given: ABCD is a parallelogram and AC = BD

To prove: ABCD is a rectangle

Proof: In Δ ACB and ΔDCB

AB = DC _____ Opposite sides of parallelogram are equal

BC = BC _____ Common side

AC = DB _____ Given

Therefore,

Δ ACB ≅ ΔDCB by S.S.S TEST

ANGLE ABC = Angle DCB ______ C.A.C.T

Now,

AB ║ DC _______ Opposite sides of parallelogram are parallel

Therefore,

Angle B + Angle C = 180 degree (Interior angles are supplementary)

Angle B + Angle B = 180

2 Angle B = 180 degree

Angle B = 90 degree

Similarly, we can prove that, Angle A = 90 degree, Angle C = 90 degree and Angle D = 90 degree.

Therefore, ABCD is a rectangle.

Answer»

Answer:

since ADJACENT angles in a ||gm are co-interior

therefore, x + x + 20= 180°

2x= 180-20

x= 160/2

x= 80

Queras The digit at tens place of a two digits numberis two times the digit at onces place. If digits arerevered, the number becomes 18 less than the originalnumber. What is the original number?Ang 9-)

Answer»

Step-by-step explanation:

let the digit at 10's place be X and digit at UNIT's place be y.

ACCORDING to 1ST and 2nd condition,

x = 2y....... (I)

by interchanging

10y + x = 10x +y - 18..... (II)

substituting value of x in equation (II)

10y + 2y = 10(2y) + y - 18

12y = 21y - 18

12y - 21y = - 18

-9y = - 18

y = 2

by putting value of y in equation (I)

x = 2(2)

x = 4

original number = 10x + y

= 10(4) + 2

= 40 + 2

= 42

Answer» $\Large{\textbf{\underline{\underline{According\;to\;the\;Question}}}}$ Assumption Original speed of train :- = p km/h Also, TIME TAKEN to cover 360 km = 360/p hours So, Time taken to cover 360 km (Combined) :- = 360/p + 5 hr Situation :- ⇒ 360/p - 360/p + 5 = 1 ⇒ 360(p + 5 - p)/p(p + 5) = 1 ⇒ 360(5) = p² + 5p ⇒ 1800 = p² + 5p ⇒ p² + 5p - 1800 = 0 ⇒ p² + 45p - 40p - 1800 = 0 ⇒ p(p + 45) - 40(p + 45) = 0 ⇒ (p + 45) (p - 40) = 0 ⇒ p = -45 Also ⇒ p = 40 [As negative value is not APPLICABLE for speed] So, ⇒ p = 40 km/hr.

So,

Time taken to cover 360 km (Combined) :-

= 360/p + 5 hr

Situation :-

⇒ 360/p - 360/p + 5 = 1

⇒ 360(p + 5 - p)/p(p + 5) = 1

⇒ 360(5) = p² + 5p

⇒ 1800 = p² + 5p

⇒ p² + 5p - 1800 = 0

⇒ p² + 45p - 40p - 1800 = 0

⇒ p(p + 45) - 40(p + 45) = 0

⇒ (p + 45) (p - 40) = 0

⇒ p = -45

Also

⇒ p = 40

[As negative value is not APPLICABLE for speed]

So,

⇒ p = 40 km/hr.

Therefore,

Speed of the train = 40 km/h
