Answer:
23
Step-by-step explanation:
Raise 3 to the power of 3
27 - 4
Subtract 4 from 27
23
Hope this was correct
4x+7=3x+18
-3x =-3x subtract 3x from both sides
x+7=18 you're left with x
-7 =-7 subtract 7 from each side
x= 11 you're left with 11 as your answer
Answer:
Option C) 4 congruent sides
Step-by-step explanation:
From the construction done as per statements given in the question.
AB is a common radius of circles A and circle B.
Since AB = AC = AD ( radii of circle A)
And AB = BC = BD (radii of circle B)
Therefore, AB = AC = AD = BD = BC
All sides of quadrilateral ABCD are equal.
Option C is the answer.
Answer: 159.5
Step-by-step explanation:
If 22% if is 9.90 you add 149.60+ 9.90 and you get 159.5. I'm sorry if this is wrong, I tried
Answer:
The correct options are;
1. Definition of supplementary angles
2. m∠1 + m∠2 = m∠1 + m∠3
3. m∠2 = m∠3
4. Definition of congruent angles
Step-by-step explanation:
The two column proof is presented as follows;
Statement
Reason
1. ∠1 and ∠2 are supplementary
Given
∠1 and ∠3 are supplementary
2. m∠1 + m∠2 = 180°
(1) Definition of supplementary angles
m∠1 + m∠3 = 180°
3. (2) m∠1 + m∠2 = m∠1 + m∠3
Transitive Property
4. (3) m∠2 = m∠3
Subtraction property of equality
5. ∠2 ≅ ∠3
(4) Definition of congruent angles
Given that angles ∠1 and ∠2 are supplementary, we have, ∠1 + ∠2 = 180°
Given that angles ∠1 and ∠3 are also supplementary, we also have, ∠1 + ∠3 = 180°
∴ ∠1 + ∠2 = 180° = ∠1 + ∠3
∠1 + ∠2 = ∠1 + ∠3
∠1 + ∠2 - ∠1 = ∠1 + ∠3 - ∠1
∴ ∠2 = ∠3
∴ ∠2 ≅ ∠3, by definition of congruent angles.
