Rule for obtuse triangle is:
c^2 > a^2+b^2
Here
7^2 > 3^2 + 6^2
49 > 9+36
49>45

So answer is True.

What is 140/216 in simplest forms
kirill115 [55]

To make a fraction to its simplest form, you have to divide the numerator and the denominator by the same number. For this question, divide 140 and 216 by 4. You will get 35/54. Since you can't divide this further, the simplest form of 140/216 is 35/54.

<em>Hope it helps</em> :)

Write the equation of the ellipse in standard form that has the following characteristics: Vertices (2,1) (2,7) and co-vertices
Darina [25.2K]

Answer:

\frac{(x - 2)^{2} }{4 } + \frac{(y - 4)^{2} }{9 } = 1

Step-by-step explanation:

Equation of an ellipse elongated vertically in standard form is\frac{(x - h)^{2} }{b^{2} } + \frac{(y - k)^{2} }{a^{2} } = 1:    for where (h, k) is the center, a is the distance

from the center to a vertex, b is the distance from the center to a co-vertex.

In your problem, the center is at (2, 4),  a = 3 and b = 2

So, the equation is  \frac{(x - 2)^{2} }{2^{2} } + \frac{(y - 4)^{2} }{3^{2} } = 1

                                \frac{(x - 2)^{2} }{4 } + \frac{(y - 4)^{2} }{9 } = 1
