Answer:

x=30, and angle A equals 132°.

Step-by-step explanation:

Since the angles are alternate-interior, both angles A and B equal the same amount. To figure out the value of x, you'd need to set up your equation like this:

5x-18°=3x+42°

You would need to solve for x, which should equal to 30.

Once you get your x, you need to plug it in into the equation of angle A, which is 5x-18°:

5(30)-18°

150-18°

Angle A = 132°.

The difference between a number and 8 is 11

quester [9]

Answer:

The difference between 19 and 8 is 11.

Step-by-step explanation:

Given:

The difference between a number and 8 is 11

Find the number.

Solution:

Let the unknown number be $=x$

The difference between the unknown number can be written as:

$x-8$

We are given that the difference =11

So we can write the equation to find $x$ as :

$x-8=11$

Using additive property to solve for $x$

Adding 8 to both sides to isolate $x$ on one side.

$x-8+8=11+8$

∴ $x=19$

∴ The unknown number = 19
