Q no 13 and 14 answer ​
GalinKa [24]

Answer:

<h2>Question 13 : x = 62°</h2>

<h2>Question 14 : x = 2</h2>

Step-by-step explanation:

Question 13

The diagram in question 13 is a triangle.

The sum of interior angles of a triangle is equal to 180°

To solve for x ;

x + 69 + 49 = 180 \\ x + 118 = 180 \\ x = 180 - 118 \\ x = 62

Question 14

(: represents ratio or /)

x/9 = 18/81

Cross Multiply

81x = 18×9

81x = 162

Divide both sides of the equation by 81

81x/81 = 162/81

x = 2

Find two consecutive odd integers whose product is 99
Illusion [34]
Let x be the first odd number.

Second odd number will be x+2

Proof:

If 3 (was) the first odd number, 3+2 would be the next which is 5.

So,

(x) (x+2) = 99
xsquare + 2x = 99
xsquare +2x - 99 = 0
xsquare +11x - 9x -99 = 0
x(x +11) -9(x + 11) = 0
(x+11) (x-9) = 0

So the two odd numbers were 9 and 11
