Answer:
Since
△
P
Q
R
is a right-angled triangle, we can use the cosine or sine or tan rule to find the
∠
P
(1) Sine
sin
∠
P
=
opposite
hypotenuse
=

13
∠
P
=
sin
−

=
67.38
(2) Cosine
cos
∠
P
=

-5 + i / 2i
-5 + i (2i) / 2i (2i)
-10i + i^2
i^2 - 10i
Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
Applying the law of cosines

substitute the given values


Is that the rest of the question? But if you took away the 5 dollars a 2.50 dollars from 32, you would have 24.50z
6m (m+2) = 0 is the factored form
m=0, m=-2 is m
Steps are on paper
