The coordinates plane is illustrated below.
<h3>How to illustrate the information?</h3>
A coordinate plane simply means the graphing system for points and lines.
Based on the information given, the area of teb triangle will be:
= 1/2 × b × h
= 1/2 × 11 × 20
= 110
Other information are attached.

So for the first question, you basically add up all of the sides. So it would be 3y+5+3y+1+2y+6+2y+3y-4+2y+2y+8+4y-2
To simplify that combine like terms so 17y+14
For the second part of the question, it's easy algebra.
Here's your problem 17y+14=77
To solve that get the variable by itself, subtract the constant, 14, from both sides.
17y+14 -14=77 -14
17y=63
Now divide each side by the coefficient, 17
y=3.71
I might be wrong in my math somewhere, but the method is the same... you might want to check it to make sure.
Answer:
a = 8.1
Step-by-step explanation:
Firstly, since we have a triangle, automatically, we have 3 interior angles
Mathematically the sum of these angles = 180
A + B + C = 180
27 + 25 + C = 180
52 + C = 180
C = 180-52
C = 128
We use the sine rule to find a
The sine rule posits that the ratio of a side to the sine of the angle facing that side is equal for all the sides of a triangle
Thus, mathematically according to the sine rule;
c/Sin C = a/Sin A
14/sin 128 = a/sin 27
a = 14sin27/sin 128 = 8.0657
which to the nearest tenth is 8.1

Answer:
MArkup $3.87
Selling Price $29.67
Step-by-step explanation:
Set up your problem like this: 25.80(.15)
Next, find the markup price by multiplying 25.80 and .15
Markup $3.87
<h3> Don't forget to move your decimal point.</h3><h3>Add your <u>markup price </u> to your <u>original price.</u></h3>
3.87+25.80+29.67
