Answer» Answer: a) vertically opposite anglea are equal => 4x° = 52° => X = 13° b) sum of linear angles is 180° => 2X + 3x = 180° => 5X° = 180° => x = 36° c) sum of TWO complementary angles = 90° => x° + 5° + x° + 15° = 90° => 2x° + 20° = 90° => 2x° = 70° => x = 35° d) 3x + 10° = 73° => 3x = 63° => x = 21° e) 5x+ x + 120° = 180° => 6x + 120° = 180° => 6x = 60° => x = 10°

Answer»

Answer:

a) vertically opposite anglea are equal

=> 4x° = 52° => X = 13°

b) sum of linear angles is 180°

=> 2X + 3x = 180°

=> 5X° = 180°

=> x = 36°

c) sum of TWO complementary angles = 90°

=> x° + 5° + x° + 15° = 90°

=> 2x° + 20° = 90°

=> 2x° = 70° => x = 35°

d) 3x + 10° = 73°

=> 3x = 63° => x = 21°

e) 5x+ x + 120° = 180°

=> 6x + 120° = 180°

=> 6x = 60° => x = 10°

THE DENOMINATOR OF A RATIONAL NUMBER IS GREATER THAN THE NUMERATOR BY 5. IF THE NUMERATOR IS INCREASED BY 11 AND THE DENOMINATOR IS DECREASED BY 3 . THE RESULT OBTAINED IS 5/2 FIND THE RATIONAL NUMBER

Answer»

Answer:- let NUMERATOR be = X

denominator = x + 5

numerator increased by 11 = 11 + x

denominator decreased by 3 = x + 5 - 3

= 2

= x + 11 + 5/2

x + 2

now cross MULTIPLY= 2 (x+11) = 3(x+2)

use the distributive property = 2x+22 = 3x+6

now group the numbers and change the signs while grouping = 2x-3x = 6-22

= -x = -16

cancel the signs as it is common = x = 16

therefore N= 16

D= 16+5=21

ANSWER=16/21

Answer» Answer: 16.4025 m^2 Step-by-step EXPLANATION: Given, Side of SQUARE, (a) = 4.05 m We know that, Area of square = (side)^2 = (a)^2 So, area of given square = (4.05)^2 = 4.05 × 4.05 = 16.4025 m^2 Hence, area of square = 16.4025 m^2

47.

The side of a square is 4.05m.Find its area . with the step please help

Answer»

Answer:

16.4025 m^2

Step-by-step EXPLANATION:

Given,

Side of SQUARE, (a) = 4.05 m

We know that,

Area of square = (side)^2 = (a)^2

So, area of given square = (4.05)^2

= 4.05 × 4.05

= 16.4025 m^2

Hence, area of square = 16.4025 m^2

a) vertically opposite anglea are equal

=> 4x° = 52° => X = 13°

b) sum of linear angles is 180°

=> 2X + 3x = 180°

=> 5X° = 180°

=> x = 36°

c) sum of TWO complementary angles = 90°

=> x° + 5° + x° + 15° = 90°

=> 2x° + 20° = 90°

=> 2x° = 70° => x = 35°

d) 3x + 10° = 73°

THE DENOMINATOR OF A RATIONAL NUMBER IS GREATER THAN THE NUMERATOR BY 5. IF THE NUMERATOR IS INCREASED BY 11 AND THE DENOMINATOR IS DECREASED BY 3 . THE RESULT OBTAINED IS 5/2 FIND THE RATIONAL NUMBER

Answer:- let NUMERATOR be = X

denominator = x + 5

numerator increased by 11 = 11 + x

denominator decreased by 3 = x + 5 - 3

= 2

= x + 11 + 5/2

x + 2

now cross MULTIPLY= 2 (x+11) = 3(x+2)

use the distributive property = 2x+22 = 3x+6

now group the numbers and change the signs while grouping = 2x-3x = 6-22

= -x = -16

cancel the signs as it is common = x = 16

therefore N= 16

D= 16+5=21

ANSWER=16/21
