Answer:
Option B) ∠DCE is congruent to ∠BCA by the Vertical Angles Theorem and 15 over 5 equals 12 over 4 shows the corresponding sides are proportional; therefore, ΔABC ~ ΔEDC by the SAS Similarity Postulate
Step-by-step explanation:
we know that
The SAS Similarity Theorem states that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar
we have that
m∠DCE≅m∠BCA -----> by vertical angles
substitute the values
----> is true
so
Two sides in triangle ABC are are proportional to two sides in triangle EDC and the included angle in both triangles are congruent
therefore
ΔABC and ΔEDC are similar by SAS Similarity Postulate
Answer:
To find the mean, you must add up all numbers in the problem, then divide the sum by however many numbers there are.
For example, 5, 8, 13, 17, 22.
The sum of these numbers is 65.
Because there are 5 numbers, you have to take 65 and divide that by 5.
65/5 = 13.
Your answer: You can use the numbers 26 and 38.
So, 36 + 28 = 64
Then, divide by 2.
64/2 = 32

The like terms are A.) 1/2a , B.) -3a, and D.) -0.7a
Like terms are terms that have the same variables and powers; coefficients do not need to match.
The variables in the above like terms are a.
