Answer:

37°

Step-by-step explanation:

figure consists of 2 6 side polygon

sum of interior angles: 180 x (6 - 2) x 2 =1440

x = 1440 - (135 + 107 + 126 + 325 + 125 + 95 + 120 + 90 + 280) = 37°

Answer:

x=37

Step-by-step explanation:

You split the figure in 2 polygons and write the equations ,knowing the sum of the angles of a polygon is (n-2)*180 where n is the number of the angles .

you write the equations

125+95+120+90+a+b=4*180=720

a+b=720-430

a+b=290

and then

135+107+126+(325-a)+(280-b)+x=720

973-(a+b)=720

973-290+x=720

683+x=720

x=720-683

x=37

What number gives a result of −5 when 9 is subtracted from the quotient of the number and 6?

My name is Ann [436]

Answer:

Step-by-step explanation:

If it gives a result of -4 then our equation will have .... = -4

If we subtract 9 from the quotient of a number and 5 we have x/5 - 9

Our equation is:

x/5 - 9 = -4 add 9 to both sides

x/5 = -4 + 9

x/5 = 5 multiply both sides by 5

x = 5(5)

x = 25

Check: 25/5 - 9 = 5-9 = -4

Answer checks as correct from information given

(3x+2)∧2=9 how do i solve this in the square root property

Irina18 [472]

$(3x+2)^2=9 \\\\9x^2+12x+4-9=0\\\\9x^2+12x-5=0\\\\a=9,\ \ b=12, \ \ c=-5$

$x_{1}=\frac{-b-\sqrt{b^2-4ac}}{2a}=\frac{-12-\sqrt{12^2-4 \cdot9 \cdot (-5)}}{2 \cdot 9}=\frac{-12-\sqrt{144+180}}{18}=\\\\=\frac{-12-\sqrt{324}}{18}=\frac{-12-18}{18}=\frac{-30}{18}=-\frac{5}{3}\\\\x_{2}=\frac{-b+\sqrt{b^2-4ac}}{2a}=\frac{-12+\sqrt{12^2-4 \cdot9 \cdot (-5)}}{2 \cdot 9}=\frac{-12+18}{18}=\frac{6}{18}=\frac{1}{3} \\\\Answer: \ x=-\frac{5}{3}\ \ and \ \ x=\frac{1}{3}$
