I added more places after the decimal in case you need to round it.
So all angles within a triangle should add up to 180, 102+31= 133 then subtract. 180-133=47
X-47
Answer:
D)
Step-by-step explanation:
sec(x) = 1/cos(x)
You know cos(x) = 1 for x=0, so sec(0) = 1.
You also know that sec(x) has vertical asymptotes where cos(x) = 0, at odd multiples of π/2. Only selection D matchest these characteristics.
#4 is B, #5 is A, and #6 is C
