Answer:
The correct answer is option A 43°
Explanation:
From the figure we can see a triangle and two exterior angles are given.
To find the value of p
Here we consider two angles be <1 and < 2, where <1 is the linear pair of angle measures 90° and <2 be the linear pair of angle measures 133°
m<1 = 180 - 90 = 90° and
<2 = 180 - 133 = 47
By using angle sum property
m<1 + m<2 + p = 180
p = 180 - (m<1 + m<2)
= 180 - (47 + 90)
= 180 - 137
= 43°
Therefore the correct answer is option A 43°
