Question

Q4. Find two numbers with a sum of 129 and a difference of 35. Q5. The third angle of an isosceles triangle is 160 less than the sum of the two equal angles. Find three angles of the triangle. Q6. The difference of two numbers is 3, and the sum of three times the larger one and twice the smaller one is 19. Find the two numbers. pls explain on paper or on text

Answer 1

let number 1 = n

number 2= m

 

n+m = 129

n= 129-m

 

n-m =35

n= 35 +m

 

129 - m = 35 +m

 

129 -35 =m+m

 

74 = 2m

 

37 = m

 

n = 129 -m =129 -37 = 92

 

number 1 = n = 92

number 2= m = 37

Answer 2

Q.4.Answer:let the 1st number = x

and 2nd number = y

according to the question-

x+y=129. - (1)

x-y= 35. -(2)

On subtracting equation (2) from (1) we get ,

2y= 94

=> y= 47

By putting value of y in equation (2) we get,

x- 47=35

=> x. = 82

So the required numbers are 82 and 47.
