In the following diagram, A || B. Use complete sentences to explain how the special angles created by the intersection of A and B by D can be used to solve for x . Solve for x , showing all of your work. Find the measure of ∠6.

79°

Step-by-step explanation:

We can see that if we add 3x+7 and 4x+5, it will total a 180 degree angle.  This allows us to solve for x.

3x+7+4x+5=180

7x+12=180

7x=180-12

7x=168

x=24

We can also see that angle six is the same as the angle 3x+7.  Since we know x=24, we can solve for those angles.

3(24)+7=

72+7=79

So <6=79 degrees

step-by-step explanation:

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
