The figure shows two intersecting lines and measures of the resulting angles write an equation to help you solve for x , then fi
ehidna [41]

<u>Given</u>:

Given that two lines are intersecting at the point.

The angles (3x - 8)° and (2x + 12)° are the angles formed by the intersection of the two lines.

We need to determine the equation to solve for x and the value of x.

<u>Equation:</u>

The two angles (3x - 8)° and (2x + 12)° are vertically opposite. Hence, the vertically opposite angles are always equal.

Hence, we have;

3x-8=2x+12

Hence, the equation is 3x-8=2x+12

<u>Value of x:</u>

The value of x can be determined by solving the equation 3x-8=2x+12

Thus, we have;

3x-8=2x+12

Subtracting both sides of the equation by 2x, we get;

x-8=12

Adding both sides of the equation by 8, we get;

x=20

Thus, the value of x is 20.

Hence, the equation and the value of x are 3 x-8=2 x+12 \ and\  x=20

Thus, Option D is the correct answer.

Question 3 options:
melomori [17]

The height of an object can be represented as a function of time.

It takes the rocket 25 seconds to hit the ground

The height function is given as:

\mathbf{h(t) = 400t - 16t^2}

When the rocket hits the ground, we have:

h(t) = 0

So, the height function becomes

\mathbf{ 400t - 16t^2 = 0}

Rewrite as:

\mathbf{ 16t^2 = 400t}

Divide both sides by 16t

\mathbf{ t = 25}

Hence, it takes the rocket 25 seconds to hit the ground
