Answer:

30 degrees

Step-by-step explanation:

∠BAC= ∠DAE (vert. opp. ∠s)

(x +10)°= (2x -10)°

x +10= 2x -10

<em>Bring</em><em> </em><em>constants</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>,</em><em> </em><em>x</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em>:</em>

2x -x= 10 +10

x= 20 <em>(</em><em>simplify</em><em>)</em>

∠BAC= (x +10)°

∠BAC= (20 +10)° <em>(</em><em>substitute</em><em> </em><em>x</em><em>=</em><em>2</em><em>0</em><em>)</em>

∠BAC= 30°

Answer:

<bac=30°

Step-by-step explanation:

<bac=<ead (being vertically oppoaite angles)

(x+10)=(2x-10)

10+10= 2x-x

20°=x

now

<bac=(x+10)°

<bac=(20+10)°

so,<bac=30°

6y+4−3y−7=3(y−1) How many solutions are for this?
Kryger [21]

Answer:

Infinite amount of solutions.

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Regular + Equality Properties

Step-by-step explanation:

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

6y + 4 - 3y - 7 = 3(y - 1)

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

  1. Combine like terms:                         3y - 3 = 3(y - 1)
  2. Distribute 3:                                       3y - 3 = 3y - 3
  3. Subtract 3y on both sides:               -3 = -3

Here we see that there will be infinite amount of solutions. We can plug in any number <em>y</em> and it will render the equation true.
