Find the value of x in the equation sin2x = sin 45° cos 45°+ sin 30°→Note:- Please don't give any unnecessary answer as well as wrong answer I request to all... and by the way it's a question of class 10's sample papers.​​​

Answer»

ANSWER:

x=45

Step-by-step EXPLANATION:

SIN2X= sin45cos45+sin30

sin2x= 1/√2×1/√2+1/2

sin2x=1/2+1/2

sin2x=1

sin2x=sin90

2x=90

x=45

ABC is a triangle through vertex A a line RQ is drawn parallel to side BC similarly PR and QP are the lines drawn through the vertex B and C parallel to AC and AB respectively to foam another triangle PQR. find the ratio of perimeter of Triangle ABC to that of triangle pqr​

Answer»

CLEARLY, ABCQ and ARBC are parallelograms.

BC=AQ and BC=AR

⇒AQ=AR

⇒A is the mid-point of QR.

Similarly, B and C are the mid-points of PR and PQ respectively.

∴AB=½ PQ,BC= ½QR and CA½ PR

⇒PQ=2AB,QR=2BC and PR=2CA

⇒PQ+QR+RP=2(AB+BC+CA)

PERIMETER of ΔPQR=2 (Perimeter of ΔABC)

A and B can paint the fence of a park in 8 days, B and C can paint the fence in 12 daC and A can paint the fence in 6 days. In how many days will (i) each one of thethe fence, (ii) all of them working together paint the fence?​

Answer»

Answer:

A+B one day work=1/8

B+C one day work= 1/12

C+A one day work= 1/6

adding all equation

2(A+B+C) one day work= 1/8+1/12+1/6

= 3+2+4/24

=9/24

A+B+C one day work=9/24*2=9/48

= 3/16

A+B+C complete work in 16/3days

A one day work = A+B+C one day work- B+C one day work

A one day work = 3/16 -1/12=9-4/48

=5/48

A complete work in 48/5

similarly

B one day work =3/16 -1/6=9-8/48

=1/48

B complete work in 48 days

similarly

C one day work =3/16 -1/8

C one day work =3-2/16=1/16

C complete work in 16 days

3) angle r = 51.05

4) angle c = 25.99

5) angle G = 37

Step-by-step explanation:

In all above cases we had to use angle sum property of triangle

cubical box has each edge 10cm and another cuboidal box is 12.5cm long,10cm wide and 8cm high. Which box has the greater surface area and by how much?

Answer»

(i) Lateral surface AREA of CUBE = 4edge

2

=4(10)

2

=400

lateral surface area of CUBOID =2H(l+b)

2×8(12.5+10)

=16×22.5

=360

So, the lateral surface area of the cube is larger by (400−360=40)cm

140 members of a football club have blue eyes 72% of the members of a football club do not have blue eyes . how many members do not have blue eyes

Answer»

GIVEN,

Number of members with BLUE eyes = 140

Percentage of members without blue eyes = 72%

To find,

The number of members who don't have blue eyes.

Solution,

We can simply solve this mathematical problem by using the FOLLOWING mathematical process.

The percentage of the members who have blue eyes = (100-72) = 28%

Now, LET the total number of members = x

So,

x × 28/100 = 140

x = 140 × 100/28

x = 500

Number of members who don't have blue eyes = (500-140) = 360

Hence, 360 members do not have blue eyes.

Can anyone say real facts about zombies​

Answer»

Hey mate !!

Here is ur Answer ⤵

️Let's know some interesting facts about Zombies :

1. Haitian Clairvius Narcisse is the most famous example of a “real-life” zombie. A voodou ritual combining powerful neurotoxins and hallucinogens puroportedly zombified Narcisse and his tale has been often repeated since.

2. The word “zombie” is thought to have been adapted from the AFRICAN word nzambi meaning 'God'. “Le Grand Zombi,” or the Grand Serpent, was the father of all gods, and appeared in the shape of a python.

3. Zombie fans are called “Zombophiles.”

4. Zombie lore dictates that there are only two WAYS to kill a zombie... go for the brain or cut off the head.

5. “Father of the modern zombie” George A. Romero is viewed as the creator of modern zombie cinema. He has directed more zombie films than anyone in history.

6. Some of the zombie make-up on Romero's seminal 1978 classic Dawn of the Dead was so evocative it made cast members physically sick.

7. Aside from humans, the unassuming ant can also be turned into a zombie. Parasitic fungus Ophiocordyceps can synchronise several ants to chew on a LEAF and then die. The fungus then sprouts through the dead ants’ bodies.

8. A law in Haiti makes it a criminal office to turn someone into a zombie. Article 249 dictates that if someone drugs another person, buries them as though they were dead, and then digs the person up and brings him back to life, it is still considered murder.

9. World Zombie Day takes place around the globe on 8th October. City centres worldwide become infested with the living dead as mass parades take place and raise money for charity.

10. Zombies by their very nature are inconsistent.

find the area off the sector of circle with radius 4 cm and the angle 30° the find the area of corresponding major sector​

Answer»

Given;

⇒Radius of CIRCLE 4CM

⇒angle(Ф) = 30°

Formula;

⇒Area of SECTOR circle = (Ф/360°)×πr²

Put the VALUE on formula

⇒(30/360)×3.14×4×4

⇒(1/12)×50.24

⇒50.24/12

⇒4.18cm²

Now we have to find Area Major sector , so we USE this formula

⇒Area of major sector = Area of circle - area of minor sector

⇒Area of major sector =πr² -   (Ф/360°)×πr²

We have already find the area of minor sector , so put the value

⇒Area of major sector = 3.414 × 4 × 4 -   4.18

⇒Area of major sector = 54.624 - 4.18 = 50.44cm²
