Answer:
Question 1: x=50°
Question 2: x=118°
Explanation:
A right angle has a total of 90 degrees
a straight line has a total of 180 degrees
Question 1:
The first problem is an example of a complementary angle. To work out the value of x you would need to Minus the angle of 40 from the total of 90, this gives you 50. This is because question 1 is a right angle and so is 90°, also by subtracting the angle form the total of 90 you are isolating the value of x.
1) Minus 40 from 90.

Question 2:
The second question is an example of a supplementary angle. To work out the value of x in the second question you would minus the angle of 62 from the total of 180, this gives you 118. This is because question 2 is a straight line and so has a total angle of 180°, also by subtracting the angle from the total we are isolating the value of x.
1) Minus 62 from 180.
