Answer» GIVEN: Sum of two CONSECUTIVE EVEN natural numbers is 26 TO FIND: The two consecutive numbers SOLUTION: Let the numbers be 'x' and 'x + 2' ACCORDING to the question, => x + x + 2 = 26 => 2x = 26 - 2 => x = 24/2 => x = 12 One NUMBER = x = 12 Another number = x + 2 = 12 + 2 = 14 Therefore, the two numbers are 12 and 14 VERIFICATION: => x + x + 2 = 26 => 12 + 12 + 2 = 26 => 26 = 26 LHS = RHS Hence, Proved!

16.

The sum of two consecutive even natural numbers is 26, what are the two numbers ?

Answer»

GIVEN:

Sum of two CONSECUTIVE EVEN natural numbers is 26

TO FIND:

The two consecutive numbers

SOLUTION:

Let the numbers be 'x' and 'x + 2'

ACCORDING to the question,

=> x + x + 2 = 26

=> 2x = 26 - 2

=> x = 24/2

=> x = 12

One NUMBER = x = 12

Another number = x + 2 = 12 + 2 = 14

Therefore, the two numbers are 12 and 14

VERIFICATION:

=> x + x + 2 = 26

=> 12 + 12 + 2 = 26

=> 26 = 26

LHS = RHS

Hence, Proved!

Answer» CORRECT question is FIND the value of b if 6+√3 by 6-√3b= 6-√3 by 6+√3 Step-by-step EXPLANATION: (6+√3)/(6-√3b)= (6-√3)/6+√3 6-√3b= (6+√3)6+√3)/(6-√3) b=. [(6+√3)²/(6-√3) - 6] / - √3 b=( 6+√3)³/33-6] /-√3 b= - (6+√3)³/33/√3+2√3 b= -√3(6+√3)³/99+2√3 b= √3[ 2- ( 6+√3)³/99] this is the answer

23.

6+√3 by 6-√3b = 6-√3 by 6+√3

Answer»

CORRECT question is FIND the value of b if 6+√3 by 6-√3b= 6-√3 by 6+√3

Step-by-step EXPLANATION:

(6+√3)/(6-√3b)= (6-√3)/6+√3

6-√3b= (6+√3)6+√3)/(6-√3)

b=. [(6+√3)²/(6-√3) - 6] / - √3

b=( 6+√3)³/33-6] /-√3

b= - (6+√3)³/33/√3+2√3

b= -√3(6+√3)³/99+2√3

b= √3[ 2- ( 6+√3)³/99]

50.	Inradius of a right triangle with hypotenuse 17cm is 3cm. What is the area of the triangle?
Answer» Step-by-step explanation: GIVEN Inradius of a right triangle with hypotenuse 17cm is 3cm. What is the AREA of the triangle? We need to find the area of the triangle So given hypotenuse = 17 CM, radius r = 3 cm Now Inradius of a right angled triangle is given by r = (P + B – H) / 2 So 3 = (P + B – 17) / 2 Or P + B – 17 = 6 Or P + B = 23 Squaring both sides we get P^2 + B^2 + 2 PB = 529 So P^2 + B^2 = h^2 Or h^2 + 2 PB = 529 17^2 + 2PB = 529 2 PB = 529 – 289 2 PB = 240 Or PB = 120 Therefore Area of the CIRCLE will be 120 sq cm Reference link will be brainly.in/question/2263632

Inradius of a right triangle with hypotenuse 17cm is 3cm. What is the area of the triangle?

Answer»

Step-by-step explanation:

GIVEN Inradius of a right triangle with hypotenuse 17cm is 3cm. What is the AREA of the triangle?

We need to find the area of the triangle
So given hypotenuse = 17 CM, radius r = 3 cm
Now Inradius of a right angled triangle is given by r = (P + B – H) / 2
So 3 = (P + B – 17) / 2
Or P + B – 17 = 6
Or P + B = 23
Squaring both sides we get
P^2 + B^2 + 2 PB = 529
So P^2 + B^2 = h^2
Or h^2 + 2 PB = 529
17^2 + 2PB = 529
2 PB = 529 – 289
2 PB = 240
Or PB = 120

Therefore Area of the CIRCLE will be 120 sq cm
