Answer:
8. x = 9
9. x = 9
10. x = 36
11. x = 8
Explanation:
Question 8
As the base of the triangle has been bisected, set the expressions either side of the perpendicular bisector equal to each other and solve for x:
Question 9
As the base of the triangle has been bisected, set the expressions either side of the perpendicular bisector equal to each other and solve for x:
Question 10
Angles on a straight line sum to 180°. Therefore, as the other angle on the line is a right angle, equate the given expression to 90° and solve for x:
Question 11
Interior angles of a triangle sum to 180°. Therefore, equate the sum of the given angles to 180° and solve for x:
