Answer:
w = 4
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
sum the 3 angles and equate to 180
13w + 18w + 56 = 180
31w + 56 = 180 ( subtract 56 from both sides )
31w = 124 ( divide both sides by 31 )
w = 4
Answer: tables cost $8 each and chairs cost $2.5 each.
Step-by-step explanation: Let c be for chairs and t be for tables...
2c + 5t = 45
8c + 3t = 44
To find t, multiply the first equation by -4 so that we can use the process of elimination:
-8c - 20t = -180
+ 8c + 3t = 44
-17t = -136 or t = 8
To find c, plug t into the original equation:
2c + 5(8) = 45
2c + 40 = 45
2c = 5
c = 2.5

Answer:
B)
Step-by-step explanation:
The isosceles triangle is simply defined as needing to have AT LEAST two sides of equal length, so the equilateral triangle is included within the category of the isosceles triangle. Thus, the best answer is B).
