The correct question is
<span>Given cos theta=4/9 and csc theta < 0 find sin theta and tan theta
</span>
we know that
csc theta=1/sin theta
if csc theta < 0
then
sin theta < 0
we have that
<span>cos theta=4/9
we know that
sin</span>² theta+cos² theta=1
so
sin² theta=1-cos² theta-----> 1-(4/9)²----> 1-(16/81)----> 65/81
sin theta=-√(65/81)---->-√65/9
the answer Part a) is
sin theta=-√65/9
Part b) find tan theta
tan theta=sin theta/cos theta
tan theta=(-√65/9)/(4/9)-----> tan theta=-√65/4
the answer part b) is
tan theta=-√65/4
Answer:
4+ 7/m
Step-by-step explanation:
there might be parentheses but this is what the expression would look like
Answer:
It will always be the case when A and B are opposites
Step-by-step explanation:
sin(x) = -sin(-x) so ...
sin(A -A) = (A -A) = sin(A) -sin(A) = 0
That is, the given expression is true when B=-A.
Answer:
8x10=80
4x8=32, 32 divided by 2 = 16
80+16= 96sq.ft
96 divided by 22 = 4.36
the answer is 5 whole quarts
