Can somebody help me please is it A, B,C, D

80 degrees

Step-by-step explanation:

The only given angle here is angle 4, which measures 100 degrees.

1) Identify angle relationships

Angle 4 and angle 6 are interior angles, meaning they have a sum of 180 degrees.

2) Solve for angle 6

180-Angle 4=Angle 6

180-100=Angle 6

80=Angle 6

Therefore, the measure of angle 6 is 80 degrees.

I hope this helps!

c. 80°

Step-by-step explanation:

We are given a shape with a bunch of lines, and are asked to find what measure is ∠6.

Solving this is simple, we just need to keep notice that what angle is larger than 90 degrees looks like and what under 90 degrees looks like. All angles that are above 90 look wide and huge, while all under is very tiny and skinny.

If we take a look at our hint, angle 4 has the (100 degrees). Look at how wide it is, if angle 6 is tinier than that, then the answers A. and B. are scratched out.

Now 90 degrees is a right angle, looking at angle 6 guarantees that D. is also not correct because it is not a right angle.

Leaving us with C. 80

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
