Answer:
E.) 1
Step-by-step explanation:
Firstly we will solve for L.H.S.
L.H.S. =
Since we know that
is the inverse of
.
So we can say that;

Now For R.H.S.

Since we can rewrite
as
.
Now we can say that the R.H.S. is;

Now we add the fraction and get;

Now according to trigonometric identity;

So, 
Here,
and
=
<em> </em>
L.H.S. = R.H.S.
Hence 
The product is multiplied by the equation im guessing
Answer:
18km/h
Step-by-step explanation:
if the riverboat is already going 15 km/h and the current is 3km/h then you should add and you get 18 km/h
Answer:
Part 1) Option C. Same side interior angles
Part 2) Option A. 
Part 3) Option B. 
Step-by-step explanation:
Part 1) we know that
If p and q are parallel
then
m<3 and m<5 are consecutive interior angles or Same side interior angles
and

Part 2) we know that
-----> by consecutive interior angles (supplementary angles)
we have that


so
substitute

Part 3) Find the measure of angle 5
we know that

Solve for x




substitute the value of x

Answer:
x=40
Step-by-step explanation:
you have to get a answer of 60
(40)+20=60
and 2(40)-20=60
