The sum of the inside angles of a 5 sided figure needs to equal 540 degrees.
Add all the angles together to equal 540 and solve for x. Once you have the value for x you can use that to figure out all the angles.
X-8 + 3x-11 + x + 8 + 2x + 7 + x = 540
Simplify by combing like terms:
8x - 4 = 540
Add 4 to both sides:
8x = 544
Divide both sides by 8:
X = 68
Now replace x with 68 in each angle and solve:
U = 68-8 = 60
V = 3(68)-11 = 204-11 = 193
W = 68 + 8 = 76
Y = 68
Z = 2(68) + 7 = 136 + 7 = 143

Negative. You have $252, and the check will take away $287, so 252-287 is -35.
Answer:
B
Step-by-step explanation:
Let the base of the triangle be <em>b</em> and the height be <em>h</em>.
The sum of the base and height is 14. Thus:
Recall that the area of a triangle is given by:
From the first equation, solve for either variable:
Substitute:
Distribute:
Distribute:
Let <em>b</em> = <em>x</em>. Hence:
Therefore, our answer is B.
