Question

6. What are the values of x and w?

he value of x is
to
wo
138°
The value of wis
m

Answer 1

• x = 29, w = 42

----------------------

According to the diagram we have:

1) Angles w and 138° form a linear pair, hence:

• w + 138 = 180
• w = 42

2) Angles 19°, x and w form a right angle, hence:

• 19 + x + 42 = 90
• 61 + x = 90
• x = 29
