Hey!
To solve x in this equation we must first add five to both sides to get

on its own.
<em>Original Equation :</em>

<em>New Equation {Added 5 to Both Sides} :</em>

Now we must square both sides of the equation.
<em>Old Equation :</em>

<em>New Equation {Changed by Squaring Both Sides} :</em>

And now we must solve the new equation.
Step 1 - Switch sides

Step 2 - Subtract x from both sides

Step 3 - Simplify

Now we need to solve the rest of the equation using the quadratic formula.






9

4
<em>So, this means that in the equation

,</em>
x = 9 <em>and </em>
x = 4.Hope this helps!

(x + 7) - (3x + 4) = x + 7 - 3x - 4 = (x - 3x) + (7 - 4) = -2x + 3
Answer: x = 150°
Step-by-step explanation:
The tangent intersects the circle's radius at a 90° angle, so ∠OAC = ∠OBC = 90°.
AOBC is a quadrilateral and we know that sum of interior angles of quadrilateral equals to 360°.
Now,
∠OAC + ∠OBC + ∠AOB + ∠ACB = 360°
90° + 90° + x + 30° = 360°
210° + x = 360°
x = 360° - 210°
x = 150°
