Answers:
<h2>17. B</h2><h2>18. B</h2>
Step-by-step explanation:
17. We need to understand what an indirect proof is. In an indirect proof, you prove a statement by showing that the negation of the statement is false.
The "then" part of the conditional is the "to prove" statement.
In an indirect proof, we assume the opposite of what we want to prove, this is also called proof by contradiction.
So if we need to prove angle A is not an obtuse angle, we will assume it is and then use the proof format to show that angle A cannot be obtuse.
<h2>The answer is B: Assume angle A is an obtuse angle</h2>
18. This question is asking us to use an indirect proof again. The "then" part of the statement is "KL > JK" and is the "to prove" statement.
We need the opposite of this, which would be assuming that KL <u><</u> JK.
<h2>The answer is B: Assume that KL <u><</u> JK</h2><h2>I'm always happy to help :)</h2>
Answer:
b = 28
Step-by-step explanation:
131 + 21 + b = 180
152 + b = 180
b = 28
answer:
7.81
Step-by-step explanation:
ohh i like these questions this is the pythagorean theorem
1) a2+b2=c2
2) 5(2)+6(2)=c2
3) 25+36=c2
4) 61=c2
5) sqr root it
6) 7.81
Here are the senteces:
If those two were both the legs they would give us the answer of 7.81
gives us only two options of answers and the other choice is putting
one of those options as a hypotenuse.So our chance for the third side
being 7.81 is 50% chance.
have a good day
When x=-4:
2(-4)+3y=4
3y=4+8
3y=12
y=4
So the ordered pair is (-4,4), I think
