Answer:
Answer:
50.2
Step-by-step explanation:
<span>The sum of the
angle of a triangle is 180 degrees. It is mentioned that Hannah drew a pattern
of equilateral triangles. Equilateral triangle has three equal sides. Also, its
angles are the same, having 60 degrees at each corner of the triangle. The answer
is a. Letter b does not qualify to be an equilateral triangle because 120
degrees times 3 is greater than 180 degrees. Letter c and d exceeds the total
number of angles at 180 degrees.</span>
Answer:
2y = 3x - 8
y = 3/2x - 4
Work
-2x + 5(3/2x - 4) = -9
-2x + 15/2x - 20 (+20) = -9 (+20)
-4/2x + 15/2x = 11
11/2x * (2/11) = 11 (2/11)
x = 2
3(2) - 2y = 8
6 (-6) - 2y = 8 (-6)
-2y = 2
y = - 1
final answer:
x = 2
y = -1
16 + 18 + 10 = 44
44 = x + 28
16 = x
x = 16
