Step-by-step explanation:

CDE = 2x, DEF = x

hexagon = 720°

720 = 115 + 145 + 160 + 90 + 2x + x

720 = 3x + 510

720 - 510 = 3x

210 = 3x

x = 210 ÷ 3

x = 70°

CDE = 2x

= 2(70)

= 140°

Answer:

see the attachment

Step-by-step explanation:

1. Two angles that sum to 90° are complementary, whether they are adjacent or not. Angles LMN and NMP are also adjacent.

2. Vertical angles created by two distinct lines are never adjacent. The sides of the angles are created by the same lines, and the angles share a vertex, but there is no ray that is a side common to both angles.

3. Angle GMK is supplementary to angle JMG.

4. Vertical angles are congruent. See question 2.

5. See question 1.

If i randomly pick a polynomial, is it more likely to have real roots or complex roots?

Vinil7 [7]

I would say you are more likely to have complex roots. If you think of graphs of polynomials, if you draw a function that doesn't pass through the x-axis, all roots are complex.

Lucas' mom is eight years older than twice his age. The sum of their ages is 77. How old are Lucas and his mom?

Rudiy27

Answer:

Age of Lucas = 23 years

Age of Lucas Mom = 54 Years

Step-by-step explanation:

In this question we have to find the age of Lucas and his Mom

Let the age of Lucas be x

According to given condition

Twice of his age 2 * x =2x

Eight years older means age + 8x

Age of his mom = Twice of his age + 8

= 2x + 8 .................(ii)

now according to second condition

Age of Lucas + Age of his mom = 77

Put the values in the condition above

x + (2x + 8) = 77

x + 2x + 8 =77

3x + 8 = 77

subtracting 8 from both sides

3x + 8 - 8 = 77 -8

3x = 69

Dividing both sides by 3

x = 69 / 3

x = 23 years

Age of Lucas = 23 years

Now from equation (i)

Age of Lucas Mom = 2(x) + 8

putting in the value we get

Age of Lucas Mom = 2 ( 23) + 8

=46 + 8

=54 Years

Age of Lucas Mom = 54 Years
