Answer:
30
Step-by-step explanation:
Triangle containing 120° and y° is an isosceles triangle.
Therefore,
y° + 120° + y° = 180°
2y° = 180° - 120°
2y° = 60°
y° = 60°/2
y ° = 30°
y = 30
No, the sum of the lengths of any two sides must be greater than the length of the third side
Answer:
That's the graph for the function f(x)= -1/2 x^2 + 7
The vertex is f(0) = 7
