Statement - Reason
Parallelogram ABCD - Given
Line AC - two points determine a line
AB║CD ; AD║BC - A parallelogram has 2 pairs of opposite sides parallel
∠1 ≅ ∠4 ; ∠2 ≅ ∠3 - line AC acts as a transversal for the parallel sides therefore, they are congruent through alternate interior angles
Line AC ≅ Line AC - Reflexive property
ΔABC ≅ ΔCDA - ASA (Angle - Side - Angle postulate)
∠D = ∠B - CPCTC (Corresponding Parts of Congruent Triangles are Congruent)
m∠1 = m∠4 ; m∠2 = m∠3 - Congruent angles have congruent measures
m∠1 + m∠2 = m∠3 + m∠4 - Addition property of equality
m∠1 + m∠2 = m∠DAB m∠3 + m∠4 = m∠BCD - Angle Addition Postulate
m∠DAB = m∠BCD - Substitution
∠DAB = ∠BCD - Congruent angles have equal measures.
Hope this helps :)
Answer: 24
Step-by-step explanation:
24 square root: 4.898979486
Let us assume the common ratio to be = x
The ratio given in the question is 3:8
The total number that has to be divided = 132 pound.
Then
3x + 8x = 132
11x = 132
x = 132/11
= 12
So
132 pound divided in the ration 3:8 = 3 * 12:8 * 12
= 36:96
So the amount of 132 pounds when divided in the ration of 3:8 will be 36 pound:96 pound.
I hope the procedure is clear
to you.
Answer:
12 minutes
Step-by-step explanation:
First we need to look at the change in the two temperatures:
86.6-80.8= 5.8
Next we know that every minute the temperature drops half of a degree so we will find how many minutes until it reaches 80.8:
5.8/0.5= 11.6
Round the answer up to 12 minutes to have a whole number and the pool will be at 80.8 degrees or lower in 12 minutes.
