Tell whether the following set is an empty set or not.
Liono4ka [1.6K]

Answer:

It is not an empty set

Step-by-step explanation:

A quadrilateral with 3 obtuse angles is possible.

A obtuse angle has a measure of more than 90 degrees and less than 180 degrees.

Let’s say three angles are measuring 91 degrees in a quadrilateral.

91 + 91 + 91 + x = 360

x = 87

The measure of the fourth angle is 87 degrees which is less than 360 degrees and is a positive integer, so it is possible.

Let's factor the following polynomial to find the roots:
 x2-13x + q = 0
 Factoring we have:
 (x-12.5) * (x + a)
 Where,
 -12.5 + a = -13
 a = -13 + 12.5
 a = -0.5
 We now look for the coefficient q:
 q = -12.5 * a
 q = -12.5 * (- 0.5)
 q = 6.25
 The polynomial will then be:
 x2-13x + 6.25 = 0
 Its roots are:
 x1 = 12.5
 x2 = 0.5
 Answer:
 The other root and the value of the coefficient are:
 0.5 and 6.25 (Respectively)
