Angle O = 72°, Angle M = 18°, Angle N = 90°

Step-by-step explanation:

According to the angle sum theorem, all interior angles of a euclidean triangle always add up to 180°.

given 5(Angle M) = Angle N, and 4(Angle M) = Angle O, you can substitute these equations into the equation defined by this theorem, Angle M + Angle N + Angle O = 180°

. Angle M + 5(Angle M) + 4(Angle M) = 180°

10(Angle M) = 180°.

then you divide. Angle M = 18°

with this statement. you can substitute this into the other equations to get the other answers.

5(18°) = Angle N, 4(18°) = Angle O.

90° = Angle N, 72° = Angle O.

step-by-step explanation:

1+2+3+4+5+6+7+8+9+10 = 55

2*10 = 20

55-20 = 35

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
