Find the perimeter of (A) an equilateral whose sidebis 15 cm. please answer the questions​

Answer»

Answer:

45

Step-by-step explanation:

To FIND the perimeter of an equilateral triangle given its AREA, we must first find the LENGTH of the sides. This can be DONE by using the equation of the area of an equilateral triangle:

Area=a²√3/4

where a is the side of the triangle.

Because the sides of the equilateral triangle are equal, the perimeter is equal to 3a.

Angles of elevation of the top of a 20 m high pole from two points in a line are 30 and 60 find the distance between the points​

Answer»

Answer:

23.094 m

Step-by-step EXPLANATION:

Here, a png file is attached.

length of the POLE AB = 20 m

ELEVATION of point A from point C = 60°   ∠ACB = 60°

elevation of point A from point D = 30°   ∠ADB = 30°

Now, tan\angle ACB= \frac{AB}{BC}  ►  BC= \frac{AB}{tan\angle ACB} = \frac{20}{tan60} = \frac{20}{\sqrt3}  m

Again,tan\angle ADB= \frac{AB}{BD}  ► BD= \frac{AB}{tan\angle ADB} = \frac{20}{tan30} = 20\sqrt3 m

Finally, DISTANCE between the points​ C & D = CD

= BD-BC

=( 20\sqrt3-\frac{20}{\sqrt{3}} ) m

= 23.094 m

9. With an average speed of 40km/hr a train reaches itsdestination in time, If it goeswith an average speed of 35km/hr, it is late by 15 minutes,The total journey is​

Answer»

Answer:

Ratio of The Average SPEED = 40 : 35 = 8 : 7.

So, Ratio of the Time TAKEN = 7 : 8.

Difference In Time = 15 min

8 - 7 = 15

1 = 15

Thus,

8 = 8 * 15 = 120 Minutes.

Second Train Takes 120 minutes (2 hours) to reach there.

Distance = 35 * 2 = 70 KM.

Solve the pair of linear equations by elimination method :4x – 3y - 25 = 0​

Answer»

Answer:

i) x + y =5 and 2x –3y = 4

By ELIMINATION method

x + y =5 ... (i)

2x –3y = 4 ... (II)

Multiplying equation (i) by (ii), we GET

2x + 2y = 10 ... (iii)

2x –3y = 4 ... (ii)

Subtracting equation (ii) from equation (iii), we get

5y = 6

y = 6/5

Putting the value in equation (i), we get

x = 5 - (6/5) = 19/5

Hence, x = 19/5 and y = 6/5

By substitution methodx + y = 5 ... (i)

Subtracting y both side, we get

x = 5 - y ... (iv)

Putting the value of x in equation (ii) we get

2(5 – y) – 3y = 4

-5y = - 6

y = -6/-5 = 6/5

Putting the value of y in equation (iv) we get

x = 5 – 6/5

x = 19/5

Hence, x = 19/5 and y = 6/5 again

(ii) 3x + 4y = 10 and 2x – 2y = 2

By elimination method

3x + 4y = 10 .... (i)

2x – 2y = 2 ... (ii)

Multiplying equation (ii) by 2, we get

4x – 4y = 4 ... (iii)

3x + 4y = 10 ... (i)

Adding equation (i) and (iii), we get

7x + 0 = 14

Dividing both side by 7, we get

x = 14/7 = 2

Putting in equation (i), we get

3x + 4y = 10

3(2) + 4y = 10

6 + 4y = 10

4y = 10 – 6

4y = 4

y = 4/4 = 1

Hence, answer is x = 2, y = 1

By substitution method

3x + 4y = 10 ... (i)

Subtract 3x both side, we get

4y = 10 – 3x

Divide by 4 we get

y = (10 - 3x )/4

Putting this value in equation (ii), we get

2x – 2y = 2 ... (i)

2x – 2(10 - 3x )/4) = 2

Multiply by 4 we get

8x - 2(10 – 3x) = 8

8x - 20 + 6x = 8

14x = 28

x = 28/14 = 2

y = (10 - 3x)/4

y = 4/4 = 1

Hence, answer is x = 2, y = 1 again.

(iii) 3x – 5y – 4 = 0 and 9x = 2y + 7

By elimination method

3x – 5y – 4 = 0

3x – 5y = 4 ...(i)

9x = 2y + 7

9x – 2y = 7 ... (ii)

Multiplying equation (i) by 3, we get

9 x – 15 y = 11 ... (iii)

9x – 2y = 7 ... (ii)

Subtracting equation (ii) from equation (iii), we get

-13y = 5

y = -5/13

Putting value in equation (i), we get

3x – 5y = 4 ... (i)

3x - 5(-5/13) = 4

Multiplying by 13 we get

39x + 25 = 52

39x = 27

x =27/39 = 9/13

Hence our answer is x = 9/13 and y = - 5/13

By substitution method

3x – 5y = 4 ... (i)

Adding 5y both side we get

3x = 4 + 5y

Dividing by 3 we get

x = (4 + 5y )/3 ... (iv)

Putting this value in equation (ii) we get

9x – 2y = 7 ... (ii)

9 ((4 + 5y )/3) – 2y = 7

Solve it we get

3(4 + 5y ) – 2y = 7

12 + 15y – 2y = 7

13y = - 5

y = -5/13

x = 4 + 5 ( -5/13)/ 3

= 4 - 25/13 / 3

= 4 × 13 - 25/13 / 3

= 27/13×3

= 27/39

= 9/13

Hence we get x = 9/13 and y = - 5/13 again.

(iv) x/2 + 2y/3 = - 1 and x – y/3 = 3

By elimination method

x/2 + 2y/3 = -1 ... (i)

x – y/3 = 3 ... (ii)

Multiplying equation (i) by 2, we get

x + 4y/3 = - 2 ... (iii)

x – y/3 = 3 ... (ii)

Subtracting equation (ii) from equation (iii), we get

5y/3 = -5

Dividing by 5 and multiplying by 3, we get

y = -15/5

y = - 3

Putting this value in equation (ii), we get

x – y/3 = 3 ... (ii)

x – (-3)/3 = 3

x + 1 = 3

x = 2

Hence our answer is x = 2 and y = −3.

By substitution method

x – y/3 = 3 ... (ii)

Add y/3 both side, we get

x = 3 + y/3 ... (iv)

Putting this value in equation (i) we get

x/2 + 2y/3 = - 1 ... (i)

(3+ y/3)/2 + 2y/3 = -1

3/2 + y/6 + 2y/3 = - 1

Multiplying by 6, we get

9 + y + 4y = - 6

5y = -15

y = - 3

Hence our answer is x = 2 and y = −3.
