<u>Geometry</u>

  • Sum of Angles: 180(n - 2)°

Step-by-step explanation:

<u>Step 1: Identify</u>

We have a polygon, so n = 4.

  1. Substitute [SA]:                    180(4 - 2)°
  2. (Parenthesis) Subtract:        180(2)°
  3. Multiply:                                360°

This tells us the sum of all angles in the shape.

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Set up equation:                     90° + 93° + 89° + x° = 360°
  2. Combine like terms:               x° + 272° = 360°
  3. Isolate <em>x</em>:                                  x = 88°

When you add their numbers together you get 207 . Jen's number is 9 more than Carrie's, and Fran's number is 3 less than Jen's n
murzikaleks [220]

Answer: Fran's number is 70

Step-by-step explanation:

Let x represent Jen's number.

Let y represent Carrie's number.

Let z represent Fran's number.

When you add their numbers together you get 207. This means that

x + y + z = 207 - - - - - - - - - -1

Jen's number is 9 more than Carrie's number. It means that

y = x - 9

Fran's number is 3 less than Jen's number. It means that

z = x - 3

Substituting y = x - 9 and z = x - 3 into equation 1, it becomes.

x + x - 9 + x - 3 = 207

3x - 12 = 207

3x = 207 + 12 = 219

x = 219/3 = 73

y = x - 9 = 73 - 9

y = 64

z = x - 3 = 73 - 3

z = 70
