Which of the following is an informal proof of the given conjecture? Conjecture: All squares are similar
Answers
Answer:
the last one, i just got 100%
Step-by-step explanation:
Option 4 : Square A has side lengths a₁ =3, a₂= 3 and Square B has side lengths b₁=6,b₂=6 Then show that the ratio of corresponding side length is equal: a₁ /a₂=b₁/b₂, 3/3=6/ 6 is the informal proof of the given conjecture.
What is informal proof?Informal proofs are used to proof a theorem in different methods of proving theorems and steps of the proof are not formally framed.
Mostly by taking a particular example a theorem is proved.
All square are similar.
This statement is true
∴ Option 1 is false
Option 2 is formal proof as sides of squares A and B are taken as variables x and y therefore this proof can be used for any pair of two squares
Option 3. is wrong proof as the two sides of square A and B are taken unequal but square has all four sides equal.
Option 4 is correct proof but it is not a formal one as a particular example is taken to proof with statement
Therefore option 4 is the correct option that show the informal proof of the given statement.

What is the angle measure of angle b?
b
67°
A) 113°
C) 157°
B) 23°
D) 67°
Answers
Answer:
23 degrees
Step-by-step explanation:
You are given a right angle, which is 90 degrees. Part of the right angle is 67 degrees, so you do 90-67=23
Hope this helps ^^
Answer:
23 degrees
Step-by-step explanation:
This is because angle B and the angle that is 67 degrees are both apart of one right angle. We can solve this through a simple equation. 90 = x +67. Subtract 67 on both sides and you get X = 23 giving you the answer 23 degrees.

what is the value of x in the equation 6x-5/2 = 2x+6
Answers
Answer:
x= 17/8
Step-by-step explanation:
6x− 5/2=2x+6
Step 1: Simplify both sides of the equation.
6x+−5/2=2x+6
Step 2: Subtract 2x from both sides.
6x+−5/2−2x=2x+6−2x
4x+−5/2=6
Step 3: Add 5/2 to both sides.
4x+−5/2+5/2=6+5/2
4x=17/2
Step 4: Divide both sides by 4.
4x/4=17/2/4
x=17/8
