In this case you the probabilities can be multiplied similarly to if you flipped a coin twice. .45 * .80 = .36
Answer:
the answer is DBC=90°
because the midpoint of the perimeter of quadrilateral is B
X = 4/3 because set y=0.
so 0=3x-4. add 4 to both sides so
4=3x. divide both sides by. 3 and you get x=4/3.
If this is supposed to be
Then this can simply be reduced to
by the double angle formula for cosine
Answer:
