the
complete question in the attached figure
Part A
we know
price poster boards----------- > $0.75
let
p------------- > number of poster boards
q------------- > money spends on poster boards----------> $2.25
q=p*0.75---------> p=q/0.75=2.25/0.75=3
the answer part A is 3
Part B
Let
x-------------- >number of paint brushes------------ > $0.95
y-------------- >number of jar of paint ------------ > $0.99
we know
0.95x+0.99y=4.87
using a graph tool
see the attached figure
the solution is the line shown in the graph
the solution must be a pair of whole numbers, <span>the only pair that meets that condition is the point (2,3)
x=2-------------- ></span>number of paint brushes
y=3-------------- >number of jar of paint
8. x = 142
10. x = 116
cuz when the angles are across from each other like that they’re congruent so they have the same angle degree
Answer:

Step-by-step explanation:
In right triangles only, the tangent of an angle is equal to its opposite side divided by its adjacent side.
Therefore, we have the following equation:

Solving, we get:

Also in right triangles only, the cosine of an angle is equal to its adjacent side divided by the hypotenuse of the triangle.

We can also use the Pythagorean theorem now that we've found BC. However, if you choose to do so, make sure you don't use a rounded value for BC, as that could cause a notable deviation in your final answer.
Using the Pythagorean theorem to verify our answers:

Answer:
m= 34
Step-by-step explanation: remember a2 plus b2 = c2
The answer is 3/10 but that’s not one of your options
