Answer:
C
Step-by-step explanation:
It is c because all the angles are below 90 degrees and isosceles only have two of the same angles
For this case we have the following expression:
(x-5) 1/2 + 5 = 2
Rewriting correctly we have:
(x-5) ^ (1/2) + 5 = 2
Clearing x we have:
(x-5) ^ (1/2) = 2-5
(x-5) ^ (1/2) = -3
(x-5) = root (-3)
x = 5 + i * root (3)
Answer:
The value of x is given by:
x = 5 + i * root (3)
