Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle =
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* =
90* = 10
we know that
A quadratic equation is a polynomial with an order of two. Its general form is
case a)
<u>The case a) is a quadratic equation</u>
case b)
<u>The case b) is a grade polynomial</u>
case c)
<u>The case c) is a grade polynomial</u>
case d)
<u>The case d) is a grade polynomial</u>
therefore
the answer is
