Vertical angles<span> are the angles opposite each other when two lines cross, so
</span>∠AOB and ∠DOC are vertical.
A) Yes, the two events are independent because P(NF|PB) = P(NF).
Answer:
31
Step-by-step explanation:
31
Simple; you want to divide 3 and 8.
3 / 8 = 0.375
And there's your answer! Remember that a fraction is just a fancy division problem! :)
Let
x-----> the measure of the angle formed by the wooden fence and grass
we know that
in a right triangle
tan x=opposite side angle x/adjacent side angle x
opposite side angle x=13 ft
adjacent side angle x=21 ft
so
tan x=13/21x=arc tan (13/21)-----> x=31.76°------> x=32°
the answer is
32 degrees
