brainly.com/question/10192511Knowing that 1+2i is a root, you also know that 1-2i is a root, so one quadratic factor is
(x -1)² -(2i)² = x^2 -2x +5
Long division of the given polynomial by this quadratic gives a quotient of
x² +9
which has roots ±3i.
Then all
the roots are {-3i, 3i, 1-2i, 1+2i}.
1 is an isosceles
2 is scalene
3 is an equilateral
Answer:
The Answer us 65 but why don't you get some answer choices little buddy
Is means equal
x percent is x/100
of means multiplication
So translating what you were given:

Solve for x

Simplify it

Multiply both sides by 5/3 to isolate x

Your final answer is
