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
It is a good idea to get familiar with the operation of your calculator. If you're going to use on-line resources to work problems like this, you can make use of any of several good on-line calculators. Google and Bing search boxes will do calculations for you while observing all the rules of the Order of Operations.
The result of this computation is a number that begins 2.56.... Since the hundredths digit is more than 4, the tenths digit is rounded to the next higher value, from 5 to 6.
Rounded to tenths, 2.1√1.488 = 2.6
