Answer:
The first option is the correct option
Step-by-step explanation:
From the question the slope AC is evaluated as


And the slope of line CB is mathematically evaluated as


Now for lines that are perpendicular to each other then the product of their slope should be equal to -1
So if

Then

i,e

Answer:
∆ABC ≅ ∆EFD by the SSS Congruence Theorem.
Step-by-step explanation:
The digram shows that 3 sides of ∆ABC are congruent to the 3 sides of ∆ EFD.
Based on the Side-Side-Side Congruence Theorem (SSS), we can conclude that both triangles are congruent to each other.
Therefore:
∆ABC ≅ ∆EFD by the SSS Congruence Theorem.
Answer:
2 7/5 or 2.5 times per day
Step-by-step explanation:
Given Deonadre runs 17 1/2 times around the reservoir in one week .
The rate per day will be the times ran in one week divided by 7 since there are seven days in one week .
Therefore
17 1/2
First change it to an improper fraction . We have
35/2
Now
35/2 /7
35/2 x 1/7
Multiply through
35/14
2 7/5 or 2.5 times
Therefore , Deonadre runs
2 7/5 times per day
