Mathematics
1 answer:

3 0

Answer:

Step-by-step explanation:

A tree diagram? I don't think so. Probably it would take a year's supply of paper to record all the possibilities. The question really is do you allow duplications and is 0 allowed to be the first digit.

I would think that both are fine.

So the total number for this number would be 10^9. There probably some sort of algorithm to reduce the number and to check if it is a legitimate choice  for this number.

Extra P./Geometry <br> Help quick! Thanks In Advance :)

The measure of angle C is 89 degrees.

<u>Step-by-step explanation:</u>

The given polygon ABCD is a quadrilateral.

<u>The property of a quadrilateral :</u>

The sum of the consecutive angles add to 180°.

In this quadrilateral, the angles B and C are consecutive angles. So, the sum of angle B and angle C is equal to 180 degree.

Given that,

  • The measure of angle B = 2x+3
  • The measure of angle C = 2x+1

<u>To find the value of x :</u>

m∠B + m∠C = 180

(2x+3) + (2x+1) = 180

4x + 4 = 180

4x = 180 - 4

4x = 176

x = 176/4

x = 44

<u>To find m∠C :</u>

m∠C = 2x + 1

⇒ 2(44)+1

⇒ 88+1

⇒ 89°

The measure of angle C is 89 degrees.
