Answer:
To begin with we know that a line must have an angle measure of 180, and those two angles in your photo are supplementary angles. Based on this you get this equation: 8x+6+118=180, the answer of that is 8x=56 simplify it to get x=7
Answer:
1500
Step-by-step explanation:
2500/5=500,*3=1500
Answer:
b
Step-by-step explanation:
Answer:
The answer is 28. I will explain below.
Step-by-step explanation:
Take a look at the angles, and determine what relationship they might be in. In this case, they are a pair of vertical angles. Recall that vertical angles are congruent, meaning the same measure. So set 3x+2 equal to 86, the equation looking like this: 3x+2=86. Now subtract the 2 from 86 to get 84, and you now have 3x=84. Divide 3x by three, and 84 by three. You should end up with x=28, and that's your answer.
If A and B are independent, then 
.
a.
b. I'm guessing the ? is supposed to stand for intersection. We can use DeMorgan's law for complements here:
c. DeMorgan's law can be used here too:
