Could a quadrilateral have 4 obtuse angles

Mathematics

No because all quadrilaterals must equal a total of 360 degrees. If you have four angles that are greater than 90 degrees the sum of all the interior angles is greater than 360 degrees therefore it cannot exist as a quadrilateral.

Consider the equation below. (if an answer does not exist, enter dne.) f(x) = 5 cos2(x) − 10 sin(x), 0 ≤ x ≤ 2π
jolli1 [7]
The given equation is a wave function. When plotted, the graph is shown in the attached picture. However, the unit is in degrees instead of radians. A unit of π  is equivalent to 180°. This plot could determine one variable if the other is given.

(x+2)^2+(x-3)^2-2x^2)
garri49 [273]

Answer:

<u>13 - 2x </u>

Step-by-step explanation:

(x +2)² + (x - 3)² - 2x²

<em>Expand.</em>

(x + 2)(x + 2) + (x - 3)(x - 3) - 2x²

x² + 2x + 2x + 4 + x² - 3x - 3x + 9 - 2x²

<em>Bring all the like terms together then simply.</em>

x² + x² - 2x² + 2x + 2x - 3x - 3x + 4 + 9

2x² - 2x² + 4x - 6x + 13

= <u>13 - 2x</u> (or <u>-2x + 13</u> )

12(x-20)=-48 what is x
Sophie [7]

Answer:

x = 16

Step-by-step explanation:

12(x - 20) = -48

Use distributive property

12*x - 12*20 = -48

12x - 240 = -48

Add 240 to both sides

12x = -48 + 240

12x = 192

Divide both sides by 12

x = 192/12

x = 16
