X would equal 10 if you're meaning it's 20/x as a fraction with the outcome of 2.
2x + 3x + 3x + 12 = 180° [Sum of all angles of a triangle is 180°]
=> 7 x = 180° - 12°
=> 7 x = 168°
=> x = 
°
=> x = 24°
? = 2x + 3x
=> 2×24° + 3×24°
=> 48° + 72°
<h3>=> 120°</h3>

Answer:
= 165/8
Step-by-step explanation:
11/2hrs = 1/5
x = 3/4
then Cristcross
x = 33/7/1/5
x = 33/8 ×5
x= 165/8
Answer:
<h2>x = 5 , x = -3</h2>
Step-by-step explanation:
x^2 - 2x = 15
x^2 - 2x - 15 = 15 - 15 (Subtract 15 from both sides.)
x^2 - 2x -15 = 0 (Simplify.)

<em>Set up & solve for a quadratic formula</em>
<h3><em>* I will solve for your first x</em></h3>
2 + root 64 / 2x 1 = 2 + root 64 / 2
root 64 = 8
= 2 + 8 / 2
= 10 / 2
= 5
<em>To solve for the second, follow the same pattern/formula for the first that I used to get 5.</em>
Negative five pi divided by two
