Answer:
120 deg
Step-by-step explanation:
I put an image of 120 deg down below.
Try comparing those two
53x2=106
250-106= 144
144/2=72
The length is 72cm
0 is the only degree that cannot work
Answer:
x=3
(Do not write a character less than what I have written; 3 is not the answer but x=3 is the answer.)
Step-by-step explanation:
Parabolas have a axis of symmetry; this is the line they are symmetrical about.
The line of symmetry will always go through the vertex.
Since your question says it is a function the line will be vertical and will be of the form x=a number.
The number is determine by the x-coordinate of the vertex.
I know the vertex of your problem is (3,-1) because it says that is the minimum point of the graph. The vertex of a parabola will always be it's maximum (this parabola is open down) or minimum (this parabola is open up).
So the axis of symmetry is just:
x=3.
You must actually write x=3.
3 is not the answer.
x=3 is the answer.
Little note down here:
(If it had said the parabola wasn't a function, the axis of symmetry would have been horizontal and therefore of the form y=a number where the number was the y-coordinate of the vertex.)
Bottom = 2x5 = 10ft
Middle = 2x6 ( 4+2) = 12
Top 4x2= 8
10ft+12ft+8ft= 30ft squared
