Find the value of x pls help
4vir4ik [10]

Answer:

x = 15°

Step-by-step explanation:

First Identify the angle of x by subtracting 180° - 120° = 60°

Always remember when you see a straight line the line measures 180°

So the angle of x = 60° but not the value of x so use the given equation to find the value of x

3x + 15 = 60°

3x  - 15 = -15°

3x = 45

x = 15°

Solve for x<br> 20 points
torisob [31]

Answer:

x = 21 units

Step-by-step explanation:

<em>The tangent squared is equal to the secant's total length multiplied by the secant's length without the part inside the circle.</em>

So here, that will look like: <em>36² = 27 * (27 + x)</em>

Expansion and multiplication gives us: <em>1296 = 729 + 27x</em>

Subtract from both sides: <em>567 = 27x</em>

Divide from both sides: x = 21.
