Question

Q no 13 and 14 answer ​

Answer 1

Answer:

Question 13 : x = 62°

Question 14 : x = 2

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
