Step-by-step explanation:
4) 35° and x° are vertical angles, so they are congruent to each other. Therefore, x°=35°. Since y°+y°+35°=180° since they are all supplementary to each other, then y°=72.5° when solved.
5) A is true. Think of two adjacent angles measured 60° and 30° that are next to each other. They add up to 90° as well.
B isn't true. Vertical angles are congruent to each other, not supplementary.
C isn't true. The statement contradicts itself. Complementary angles add up to 90° while supplementary angles add up to 180°

Answer: x=5/3
Step-by-step explanation:
For this problem, we can use teh information given to write out an equation and solve. Let's use x for the unknown number.
5x+5=2x+10
The left side of the equation comes from the part that says "five times a number plus 5". That is modeled above. The right side of the equation comes from "has the same value as twice the number plus 10".
5x+5=2x+10 [subtract both sides by 2x]
3x+5=10 [subtract both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we have found the unknown number, x=5/3.

Answer:
Step-by-step explanation:
In propositional logic and Boolean algebra, De Morgan's laws are a pair of transformation rules that are both valid rules of inference. ... The rules allow the expression of conjunctions and disjunctions purely in terms of each other via negation.
