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 ;
[tex]x + 69 + 49 = 180 \\ x + 118 = 180 \\ x = 180 - 118 \\ x = 62[/tex]
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
