Quadrilateral ABCD is inscribed in a circle<br> What is the measure of angle A?
Katen [24]

Answer:

Quadrilateral ABCD is inscribed in a circle, then

A + C = 180

=> 2x + 9 + 3x + 1 = 180

=> 5x = 170

=> x = 34

=> A  = 2 x 34 + 9 = 77 deg

Hope this helps!

They want me to put something here and the question is the picture
arsen [322]

Answer:

D. (1, -2)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define systems</u>

5x - 2y = 9

3x + 4y = -5

<u>Step 2: Rewrite systems</u>

10x - 4y = 18

3x + 4y = -5

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Add to equations together:                    13x = 13
  2. Divide 13 on both sides:                          x = 1

<u>Step 4: Solve for </u><em><u>y</u></em>

  1. Define:                              3x + 4y = -5
  2. Substitute in <em>x</em>:                 3(1) + 4y = -5
  3. Multiply:                            3 + 4y = -5
  4. Isolate <em>y </em>term:                  4y = -8
  5. Isolate <em>y</em>:                           y = -2

And we have our final answer!
