Answer:
B) 116°
Step-by-step explanation:
y=180-54-64=62
x=180-62-64=54
62+54=116
Answer:
The answer to your question is: letter D
Step-by-step explanation:
First we need to find the distances between the points,
distance AB = 8 get it just by counting the points in the graph
distance AC = 9 get it just by counting the points in the graph
To know the distance BC, use the pythagorean theorem
c2 = a2 +b2
c2 = 8² + 9²
c² = 64 + 81
c² = 145
c = 12.04
Finally, perimeter = AB + AC + BC
= 8 + 9 + 12.04
= 29.04 units
Answer:
No because the base could be a different shape.
