Answer:

1) 102

2) x = 31°; y = 6

3) m = 28°, n = 31°

4) x = 79°

Step-by-step explanation:

1) Angle ABD = 180 - 2(69) = 42

Angle DBC = 180/3 = 60

Angle ABC = 42 + 60 = 102

2) Angle ABC = 180 - 2(59) = 62

x = 62/2

x = 31°

ABD and CBD are congruent triangles so y = 6

3) 118 = m + 90

Exterior angle = sum of interior angles

m = 118 - 90 = 28°

n = (180-118)/2 = 31°

4) x = (180-22)/2 = 79°

What are the zeros of the polynomial function? <br><br> F(x)= x^2 + 12x +20
vampirchik [111]

Answer:

<h2>x = -2 and x = -10</h2>

Step-by-step explanation:

F(x)=x^2+12x+20\\\\\text{The zeros:}\\\\F(x)=0\iff x^2+12x+20=0\\\\x^2+2x+10x+20=0\\\\x(x+2)+10(x+2)=0\\\\(x+2)(x+10)=0\iff x+2=0\ \vee\ x+10=0\\\\x+2=0\qquad\text{subtract 2 from both sides}\\\boxed{x=-2}\\\\x+10=0\qquad\text{subtract 10 from both sides}\\\boxed{x=-10}
