Answer:
option B) ΔABE ∼ ΔADC
Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
If two triangles are similar, then its corresponding sides are proportional and its corresponding angles are congruent
In this problem
Triangles ABE and ADC are similar by AA Similarity Theorem
because
m∠ ABE≅m∠ADC
m∠ BAE≅m∠DAC
The corresponding sides are
AB and AD
BE and DC
AE and AC
so

The degrees of freedom in testing for differences between the means of two dependent populations where the variance of the differences is unknown are: df = n - 1
<h3>What is the degree of freedom for dependent variables?</h3>
In statistics, degrees of freedom refers to the number of distinct values that can change in an evaluation without exceeding any constraints.
The degree of freedom is crucial and necessary when attempting to comprehend the significance of a test statistic and the validity of the null hypothesis.
In testing for differences between the means of two dependent populations where the variance of the differences is unknown, the degrees of freedom are: df = n - 1

2x-5y=16 =>10x-25y=80
5x+3y=9 => 10x+6y=18
subtract one from the other: (6-(-25)y=(18-80), 31y=-62, y=-2
plug y=-2 in 2x-5y=16 to find x: 2x+10=16, x=3
12x+y=12*3-2=34
Answer:
√5 + π = 537766063.1 ×
Step-by-step explanation:
given data
√5 ≈ 2.2360679775
π ≈ 3.1415926535
to find out
√5 + π
solution
√5 + π = 2.2360679775 + 3.1415926535
√5 + π = 5.3776606310
√5 + π = 5.3776606310 × 
√5 + π = 537766063.1 ×
