Answer:

x = 374/7

Step-by-step explanation:

all of the angles should equal to 360 degrees since it's a quadrilateral.

So,

1+ (2x+10)+(3x-5)+(2x-20) = 360

1+ 2x+10 +3x-5+2x-20 = 360

7x -14 =360

7x = 360+14

7x = 374

x= 374/7

x= 53.428...

Hope this helps!

Solve each of the following quadratic equations 3x=0.5x^2 0=5x^2-2x+6

UNO [17]

Question 1

$3x=0.5x^{2}\\\\6x=x^{2} \\ \\ x^{2}-6x=0 \\ \\ x(x-6)=0 \\ \\ \boxed{x=0, 6}$

Question 2

$0=5x^{2}-2x+6 \\ \\ x=\frac{2 \pm \sqrt{(-2)^{2}-4(5)(6)}}{2} \\ \\ x=\frac{2 \pm \sqrt{-116}}{10} \\ \\ x=\frac{2 \pm 2i\sqrt{29}}{10} \\ \\ \boxed{x=\frac{1 \pm i\sqrt{29}}{5}}$
