Answer:
Step-by-step explanation:
The area of a circle is :A= π r² r : the radius
A= 8π square units
so : π r² = 8π
r² = 8
r = √8 = √(4 × 2) =√4×√2
r = 2√2 units
Answer:
Therefore the correct assembling is
3.∠DAC ≅ ∠BCA 3. Alternate interior Angles are Equal as AD || BC.
Step-by-step explanation:
Given:
AD ≅ BC and AD || BC
To Prove:
ABCD is a Parallelogram
Proof:
Alternate Interior Angles Theorem :
"When two parallel lines are cut by a transversal , the resulting alternate interior angles are congruent.
Here AD || BC and the transversal is AC
Statement Reasons
1. AD ≅ BC . 1. Given
2. AD || BC 2. Given
3.∠DAC ≅ ∠BCA 3. Alternate interior Angles are Equal as AD || BC.
Therefore the correct assembling is
3.∠DAC ≅ ∠BCA 3. Alternate interior Angles are Equal as AD || BC.
Answer:
I think its A, Because if you look at the problome A makes sense
Answer:
3x + 12
Step-by-step explanation:
Use the distributive property.
3(x + 4) = 3 * x + 3 * 4 = 3x + 12
Answer: 3x + 12
Answer:21
Step-by-step explanation: plug in 19 and 1
1x3 is 3 plus 19 is 21
