A side of the triangle below has been extended to form an exterior angle of 132°. Find
the value of a.
132°

Answer:
x=42
Step-by-step explanation:
so they u the exterior angle is 132
line makes 180 degree
180-132 =48
now they tell u a right angle
that is 90
triangles interior angles add up to 180
180-90-48=
42
[tex]x + 90 = 132[/tex]
(exterior angle property)
[tex]x = 132 - 90[/tex]
[tex]x = 42[/tex]
